Description

DETECTION OF HUMAN PAPILLOMA VIRUS (HPV) UTILIZING
INVASIVE CLEAVAGE STRUCTURE ASSAYS

FIELD OF THE INVENTION
The present invention provides methods and composition related to nucleic acid detection assays for use in basic research, clinical research, and for the development of clinical detection assays. In particular, the present invention provides methods for characterizing human papillomavirus (HPV) sequences.
BACKGROUND
Cervical cancer accounts for nearly 10% of all female cancers and is a leading cause of cancer among women in developing countries (Franco, E.L. et al., Can Med Assoc J.
2001;164:1017-25). The regions with the highest incidence of the disease are generally those with the greatest mortality and include Central America, Africa, and the Carribean (Ferlay, J. et al., 1998. IARC CancerBase no. 3. Lyon:IARCPress.). Incidence in Europe and North America has declined precipitously over the past 50 years, possibly due to the advent of routine screening by Papanicolaou (Pap) smear testing (reviewed in Franco et al., ibid). Cervical cancer is one of the most preventable cancers, with survival being directly related to the stage of the disease at diagnosis. The 5-year survival rate is 88% for women having initial diagnosis of localized disease as opposed to 13% for women diagnosed with distant disease (Report of the Gynecologic Cancers Progress Review Group, November 2001, National Cancer Institute). More than 50% of women diagnosed with cervical cancer in the U.S. have not had a Pap smear in the past three years (Wright, T.C. et al., JAMA.
2000; 283:81-6).
Pap screening remains the predominant mode of detecting cancerous and precancerous cervical lesions; more than 50 million women undergo Pap screening each year in the U.S. (Wright, T.C. et al., JAMA 2002; 287:2120-29). Despite its widespread use, Pap smear testing is only partially effective; some estimates place the sensitivity of conventional Pap smear testing at 50-60% (Lorincz, A.T. and Richart, R.M., (Arch Pathol Lab Med. 2003;127:959-68; Nanda, K, et al., 2000. Ann Intern Med 132:810.;
Fahey MT, et al. Am J Epidemiol. 1995;141:680-9; Myers ER, McCrory DC, Subramanian S, et al.
Obstet Gynecol. 2000;96:645-52.) or 70-80% (Clavel, C. et al., 2001. Br J
Cancer 84:1616). Recent innovations in cytological screening and sampling, such as liquid-based tests, have improved the sensitivity of these methods to 75-95% (Lorincz, A.T.
et al. ibid;
Nanda, K. et al., ibid.; Hutchinson ML, Zahniser DJ, Sherman ME, et al.
Cancer.
1999;87:48-55.). Nonetheless, even these improved methods fail to detect a significant portion of abnormal, and often precancerous, cells. Once identified, patients with atypical squamous cells of undetermined significance (ASCUS) are subjected to various levels of monitoring and treatment, depending on the particular attendant risk factors and clinical presentation (reviewed in Wright, T.C. et al. JAMA 2002, ibid).
Human Papillomavirus (HPV) has been identified as the primary, and possibly only, cause of cervical cancer (Munoz N,Bosch FX,de Sanjose S, et al., Int J Cancer 1992;52:743-9; Bosch FX, Lorincz A, Munoz N, Meijer Shah KV., Clin Pathol 2002;55:244-65), implicated in as many as 99.7% of all cases (Wallboomers, J.M. et al., 1999. J Pathol 189:12-19). The HPV genome is an 8 kb, circular, double stranded DNA
comprising 8 genes, all encoded on the same strand. As many as 200 different HPV types have been identified in humans (Burd, E.M. Clin Microbiol Rev. 2003;16:1-17);
of these approximately 40 types have been found capable of infecting the genital tract (Munoz, N. N
Engl J Med 2003;348:518-27.). Still further classification has resulted in the identification of high- and low-risk viral types for development of cervical cancer.
Estimates place the number of high-risk types between 13-19 strains, with two strains, HPV 16 and 18 together accounting for as much as 55-85% of infections, depending on subject age and geographical location (Munoz, N., ibid). The predominant low-risk strains are HPV 6 and 11;
these may lead to genital warts (reviewed in Burd, E.M., ibid).
The elucidation of certain high risk HPV strains as the causative agents of cervical cancer, coupled with advances in molecular biological methods, has expanded the spectrum of methods available for both preventing and detecting HPV infection. Vaccines for the most common high-risk HPV strains are currently in clinical trials (Koutsky, LA. et al., 2002. NEJM 347:1645-51). Moreover, some authorities are calling for HPV DNA
screening for use in conjunction with, or in some cases, in lieu of, conventional cytological methods (Wright, T.C. and Schiffinan, M. N. Engl. J. Med, 2003; 348: 489-90).
Various alternative DNA-based detection methods have been introduced, including the HYBRID
CAPTURE II (HCII) test (Digene, Gaithersburg, MD), which was been approved by the FDA in March, 1999. The HYBRID CAPTURE method relies on hybridization of target DNA to complementary RNA probes. The resultant RNA-DNA hybrids are recognized by surface-bound antibodies as well as antibodies conjugated to alkaline phosphatase, allowing generation of a chemiluminescent signal in the presence of appropriate substrates (Lorincz, A. T. J Obstet Gynaecol Res. 1996;22:629-36; also U.S. Pat. No. 4,908,306 and related patents and applications). Further alternative methods include the use of sequence specific probes for use in PCR or sandwich hybridization assays, such as those described in U.S.
6,583,278. Other methods rely on various PCR primers for selective amplification of specific strains, as in U.S. Pat. No. 5,447,839 and related applications.
Still other methods rely on in situ hybridization of sequence-specific probes to isolated cervical cells, described in WO 00/24760A1 (e.g. INFORM HPV, Ventana Medical Systems, Inc., Tuscon, AZ;
Qureshi MN et al., Diagn. Cytopathol. 2003;29:149-155).
Therefore, there exists a need for a rapid, sensitive, and highly quantitative direct detection assay for detecting HPV infection by high risk strains in cervical samples. Given the current reliance on molecular methods, it is likely that there will be an ongoing and increasing need for rapid, quantitative methods of detecting HPV infection.

In some embodiments, the present invention provides methods and kits configured to detect more than one HPV strain in a single reaction vessel (e.g., kits and methods to detect all high risk strains in four or fewer reactions). Thus, the present invention provides kits and methods comprising pooled detection assay components. In some preferred embodiments, a single oligonucleotide in the pooled detection assay components is configured to take part in an invasive cleavage structure in the presence of two or more HPV target strains.

assays, and sandwich hybridization assays.
The present invention also provides methods of detecting target nucleic acids through the use of probe sequences that are not completely complementary to the target nucleic acid. For example, the present invention provides kits and methods for detecting a target sequence by using mismatch probe sequences, comprising the steps of. a) providing a sample suspected of containing a target nucleic acid; b) exposing the sample to one or more oligonucleotides that contain a region that is complementary to said target nucleic acid, said region having a first portion completely complementary to said target nucleic acid, a second portion contiguous to said first portion that is not complementary to said target nucleic acid (e.g., a mismatch), and a third portion contiguous to said second portion that is completely complementary to the target nucleic acid; and c) detecting the target nucleic acid under conditions such that no sequences that are completely complementary to the one or more oligonucleotides or said region of the one or more oligonucleotides are detected (i.e., only sequences that are not completely complementary to the oligonucleotides or the region of the oligonucleotides are detected). Thus, even if the sample contains perfect complements to the oligonucleotides or to the region, such perfect complements are not detected. This can be carried out, for example, through use of two or more oligonucleotides that, through their coordinated action, provide specificity for the non-matched target sequence, but do not detect the perfect complement. The INVADER assay, methods employing ligation, the polymerase chain reaction, etc. are examples of methods that permit such detection. This can also be carried out with a single probe sequence in a hybridization method if the probe is of sufficient length to ensure that it is not completely complementary to any sequence in the sample that might be detected.
In some embodiments, the region of the one or more oligonucleotides contains two or more mismatches to the target nucleic acid (e.g., 3, 4, 5, 6, . . .). In some embodiments, the region contains no more than twenty (e.g., no more than 15, 12, 10, 9, 8, 7, 6,. ..) contiguous nucleotides that are completely complementary to the target nucleic acid. In some embodiments, one or more of the oligonucleotides are generated by extending a primer in an enzymatic extension reaction using the target nucleic acid as a template (e.g., in a polymerase chain reaction). In some embodiments, the target nucleic acid is a viral target nucleic acid (e.g., HPV). In some embodiments, the target nucleic acid is a conserved region of a viral genome (i.e., a region that is highly conserved between different strains or family members of the virus). For example, the LCR, E6, and E7 regions of the HPV
genome contain conserved sequences.

In particularly preferred embodiments, the reagents comprise a first and/or a third oligonucleotide labeled with moieties that produce a fluorescence resonance energy transfer (FRET) effect.
In some embodiments one or more the INVADER assay reagents may be provided in a predispensed format (i.e., premeasured for use in a step of the procedure without re-measurement or re-dispensing). In some embodiments, selected INVADER assay reagent components are mixed and predispensed together. In preferred embodiments, predispensed assay reagent components are predispensed and are provided in a reaction vessel (including but not limited to a reaction tube or a well, as in, e.g., a microtiter plate). In particularly preferred embodiments, predispensed INVADER assay reagent components are dried down (e.g., desiccated or lyophilized) in a reaction vessel.
In some embodiments, the INVADER assay reagents are provided as a kit. As used herein, the term "kit" refers to any delivery system for delivering materials.
In the context of reaction assays, such delivery systems include systems that allow for the storage, transport, or delivery of reaction reagents (e.g., oligonucleotides, enzymes, etc. in the appropriate containers) and/or supporting materials (e.g., buffers, written instructions for performing the assay etc.) from one location to another. For example, kits include one or more enclosures (e.g., boxes) containing the relevant reaction reagents and/or supporting materials. As used herein, the term "fragmented kit" refers to delivery systems comprising two or more separate containers that each contains a subportion of the total kit components.
The containers may be delivered to the intended recipient together or separately. For example, a first container may contain an enzyme for use in an assay, while a second container contains, oligonucleotides.

In some embodiments, the kits provide a sub-set of the required components, wherein it is expected that the user will supply the remaining components. In some embodiments, the kits comprise two or more separate containers wherein each container houses a subset of the components to be delivered. For example, a first container (e.g., box) may contain an enzyme (e.g., structure specific cleavage enzyme in a suitable storage buffer and container), while a second box may contain oligonucleotides (e.g., INVADER oligonucleotides, probe oligonucleotides, control target oligonucleotides, etc.).
The term "label" as used herein refers to any atom or molecule that can be used to provide a detectable (preferably quantifiable) effect, and that can be attached to a nucleic acid or protein. Labels include but are not limited to dyes; radiolabels such as 32P; binding moieties such as biotin; haptens such as digoxgenin; luminogenic, phosphorescent or fluorogenic moieties; mass tags; and fluorescent dyes alone or in combination with moieties that can suppress or shift emission spectra by fluorescence resonance energy transfer (FRET). Labels may provide signals detectable by fluorescence, radioactivity, colorimetry, gravimetry, X-ray diffraction or absorption, magnetism, enzymatic activity, characteristics of mass or behavior affected by mass (e.g., MALDI time-of-flight mass spectrometry), and the like. A label may be a charged moiety (positive or negative charge) or alternatively, may be charge neutral. Labels can include or consist of nucleic acid or protein sequence, so long as the sequence comprising the label is detectable.
As used herein, the term "distinct" in reference to signals refers to signals that can be differentiated one from another, e.g., by spectral properties such as fluorescence emission wavelength, color, absorbance, mass, size, fluorescence polarization properties, charge, etc., or by capability of interaction with another moiety, such as with a chemical reagent, an enzyme, an antibody, etc.
As used herein, the terms "complementary" or "complementarity" are used in reference to polynucleotides (i.e., a sequence of nucleotides such as an oligonucleotide or a target nucleic acid) related by the base-pairing rules. For example, for the sequence " 5'-A-G-T-3'," is complementary to the sequence " 3'-T-C-A-S'." Complementarity may be "partial," in which only some of the nucleic acids' bases are matched according to the base pairing rules. Or, there may be "complete" or "total" complementarity between the nucleic acids. The degree of complementarity between nucleic acid strands has significant effects on the efficiency and strength of hybridization between nucleic acid strands.
This is of particular importance in amplification reactions, as well as detection methods that depend upon binding between nucleic acids. Either term may also be used in reference to individual nucleotides, especially within the context of polynucleotides. For example, a particular nucleotide within an oligonucleotide may be noted for its complementarity, or lack thereof, to a nucleotide within another nucleic acid strand, in contrast or comparison to the complementarity between the rest of the oligonucleotide and the nucleic acid strand.
The term "homology" and "homologous" refers to a degree of identity. There may be partial homology or complete homology. A partially homologous sequence is one that is less than 100% identical to another sequence.
As used herein, the term "hybridization" is used in reference to the pairing of complementary nucleic acids. Hybridization and the strength of hybridization (i.e., the strength of the association between the nucleic acids) is influenced by such factors as the degree of complementary between the nucleic acids, stringency of the conditions involved, and the Tm of the formed hybrid. "Hybridization" methods involve the annealing of one nucleic acid to another, complementary nucleic acid, i.e., a nucleic acid having a complementary nucleotide sequence. The ability of two polymers of nucleic acid containing complementary sequences to find each other and anneal through base pairing interaction is a well-recognized phenomenon. The initial observations of the "hybridization" process by Marmur and Lane, Proc. Natl. Acad. Sci. USA 46:453 (1960) and Doty et al., Proc. Natl. Acad. Sci. USA 46:461 (1960) have been followed by the refinement of this process into an essential tool of modem biology.
The complement of a nucleic acid sequence as used herein refers to an oligonucleotide which, when aligned with the nucleic acid sequence such that the 5' end of one sequence is paired with the 3' end of the other, is in "antiparallel association." Certain bases not commonly found in natural nucleic acids may be included in the nucleic acids of the present invention and include, for example, inosine and 7-deazaguanine.
Complementarity need not be perfect; stable duplexes may contain mismatched base pairs or unmatched bases. Those skilled in the art of nucleic acid technology can determine duplex stability empirically considering a number of variables including, for example, the length of the oligonucleotide, base composition and sequence of the oligonucleotide, ionic strength and incidence of mismatched base pairs.
As used herein, the term " Tm " is used in reference to the "melting temperature."
The melting temperature is the temperature at which a population of double-stranded nucleic acid molecules becomes half dissociated into single strands. Several equations for calculating the T,,, of nucleic acids are well known in the art. As indicated by standard references, a simple estimate of the T,,, value may be calculated by the equation: Tm = 81.5 + 0.41(% G + C), when a nucleic acid is in aqueous solution at 1 M NaCl (see e.g., Anderson and Young, Quantitative Filter Hybridization, in Nucleic Acid Hybridization (1985). Other references (e.g., Allawi, H.T. & SantaLucia, J., Jr.
Thermodynamics and NMR of internal G.T mismatches in DNA. Biochemistry 36, 10581-94 (1997) include more sophisticated computations which take structural and environmental, as well as sequence characteristics into account for the calculation of Tm.
The term "gene" refers to a DNA sequence that comprises control and coding sequences necessary for the production of an RNA having a non-coding function (e.g., a ribosomal or transfer RNA), a polypeptide or a precursor. The RNA or polypeptide can be encoded by a full length coding sequence or by any portion of the coding sequence so long as the desired activity or function is retained.
The term "wild-type" refers to a gene or a gene product that has the characteristics of that gene or gene product when isolated from a naturally occurring source. A
wild-type gene is that which is most frequently observed in a population and is thus arbitrarily designated the "normal" or "wild-type" form of the gene. In contrast, the term "modified"
"mutant" or "polymorphic" refers to a gene or gene product which displays modifications in sequence and or functional properties (i.e., altered characteristics) when compared to the wild-type gene or gene product. It is noted that naturally-occurring mutants can be isolated;
these are identified by the fact that they have altered characteristics when compared to the wild-type gene or gene product.
The term "recombinant DNA vector" as used herein refers to DNA sequences containing a desired heterologous sequence. For example, although the term is not limited to the use of expressed sequences or sequences that encode an expression product, in some embodiments, the heterologous sequence is a coding sequence and appropriate DNA
sequences necessary for either the replication of the coding sequence in a host organism, or the expression of the operably linked coding sequence in a particular host organism. DNA
sequences necessary for expression in prokaryotes include a promoter, optionally an operator sequence, a ribosome binding site and possibly other sequences.
Eukaryotic cells are known to utilize promoters, polyadenlyation signals and enhancers.
The term "oligonucleotide" as used herein is defined as a molecule comprising two or more deoxyribonucleotides or ribonucleotides, preferably at least 5 nucleotides, more preferably at least about 10-15 nucleotides and more preferably at least about 15 to 30 nucleotides. The exact size will depend on many factors, which in turn depend on the ultimate function or use of the oligonucleotide. The oligonucleotide may be generated in any manner, including chemical synthesis, DNA replication, reverse transcription, PCR, or a combination thereof. In some embodiments, oligonucleotides that form invasive cleavage structures are generated in a reaction (e.g., by extension of a primer in an enzymatic extension reaction).
Because mononucleotides are reacted to make oligonucleotides in a manner such that the 5' phosphate of one mononucleotide pentose ring is attached to the 3' oxygen of its neighbor in one direction via a phosphodiester linkage, an end of an oligonucleotide is referred to as the "5' end" if its 5' phosphate is not linked to the 3' oxygen of a mononucleotide pentose ring and as the "3' end" if its 3' oxygen is not linked to a 5' phosphate of a subsequent mononucleotide pentose ring. As used herein, a nucleic acid sequence, even if internal to a larger oligonucleotide, also may be said to have 5' and 3' ends. A first region along a nucleic acid strand is said to be upstream of another region if the 3' end of the first region is before the 5' end of the second region when moving along a strand of nucleic acid in a 5' to 3' direction.
When two different, non-overlapping oligonucleotides anneal to different regions of the same linear complementary nucleic acid sequence, and the 3' end of one oligonucleotide points towards the 5' end of the other, the former may be called the "upstream"
oligonucleotide and the latter the "downstream" oligonucleotide. Similarly, when two overlapping oligonucleotides are hybridized to the same linear complementary nucleic acid sequence, with the first oligonucleotide positioned such that its 5' end is upstream of the 5' end of the second oligonucleotide, and the 3' end of the first oligonucleotide is upstream of the 3' end of the second oligonucleotide, the first oligonucleotide may be called the "upstream" oligonucleotide and the second oligonucleotide may be called the "downstream"
oligonucleotide.
The term "primer" refers to an oligonucleotide that is capable of acting as a point of initiation of synthesis when placed under conditions in which primer extension is initiated.
An oligonucleotide "primer" may occur naturally, as in a purified restriction digest or may be produced synthetically.
A primer is selected to be "substantially" complementary to a strand of specific sequence of the template. A primer must be sufficiently complementary to hybridize with a template strand for primer elongation to occur. A primer sequence need not reflect the exact sequence of the template. For example, a non-complementary nucleotide fragment may be attached to the 5' end of the primer, with the remainder of the primer sequence being substantially complementary to the strand. Non-complementary bases or longer sequences can be interspersed into the primer, provided that the primer sequence has sufficient complementarity with the sequence of the template to hybridize and thereby form a template primer complex for synthesis of the extension product of the primer.
The term "cleavage structure" as used herein, refers to a structure that is formed by the interaction of at least one probe oligonucleotide and a target nucleic acid, forming a structure comprising a duplex, the resulting structure being cleavable by a cleavage means, including but not limited to an enzyme. The cleavage structure is a substrate for specific cleavage by the cleavage means in contrast to a nucleic acid molecule that is a substrate for non-specific cleavage by agents such as phosphodiesterases which cleave nucleic acid molecules without regard to secondary structure (i.e., no formation of a duplexed structure is required).
The term "cleavage means" or "cleavage agent" as used herein refers to any means that is capable of cleaving a cleavage structure, including but not limited to enzymes.
"Structure-specific nucleases" or "structure-specific enzymes" are enzymes that recognize specific secondary structures in a nucleic molecule and cleave these structures. The cleavage means of the invention cleave a nucleic acid molecule in response to the formation of cleavage structures; it is not necessary that the cleavage means cleave the cleavage structure at any particular location within the cleavage structure.
The cleavage means may include nuclease activity provided from a variety of sources including the Cleavase enzymes, the FEN-1 endonucleases (including RAD2 and XPG proteins), Taq DNA polymerase and E. coli DNA polymerase I. The cleavage means may include enzymes having 5' nuclease activity (e.g., Taq DNA polymerase (DNAP), E.
coh DNA polymerase D. The cleavage means may also include modified DNA
polymerases having 5' nuclease activity but lacking synthetic activity.
Examples of cleavage means suitable for use in the method and kits of the present invention are provided in U.S. Patent Nos. 5,614,402; 5,795,763; 5,843,669; 6,090; PCT Appln. Nos WO
98/23774; WO 02/070755A2; and W00190337A2.

The term "non-target cleavage product" refers to a product of a cleavage reaction that is not derived from the target nucleic acid. As discussed above, in the methods of the present invention, cleavage of the cleavage structure generally occurs within the probe oligonucleotide. The fragments of the probe oligonucleotide generated by this target nucleic acid-dependent cleavage are "non-target cleavage products."
The term "probe oligonucleotide" refers to an oligonucleotide that interacts with a target nucleic acid to form a cleavage structure in the presence or absence of an INVADER
oligonucleotide. When annealed to the target nucleic acid, the probe oligonucleotide and target form a cleavage structure and cleavage occurs within the probe oligonucleotide.

In some embodiments, the INVADER oligonucleotide contains sequences at its 3' end that are substantially the same as sequences located at the 5' end of a probe oligonucleotide.
The term "cassette" as used herein refers to an oligonucleotide or combination of oligonucleotides configured to generate a detectable signal in response to cleavage of a probe oligonucleotide in an INVADER assay. In preferred embodiments, the cassette hybridizes to a non-target cleavage product from cleavage of the probe oligonucleotide to form a second invasive cleavage structure, such that the cassette can then be cleaved.
In some embodiments, the cassette is a single oligonucleotide comprising a hairpin portion (i.e., a region wherein one portion of the cassette oligonucleotide hybridizes to a second portion of the same oligonucleotide under reaction conditions, to form a duplex). In other embodiments, a cassette comprises at least two oligonucleotides comprising complementary portions that can form a duplex under reaction conditions. In preferred embodiments, the cassette comprises a label. In particularly preferred embodiments, cassette comprises labeled moieties that produce a fluorescence resonance energy transfer (FRET) effect.
The term "substantially single-stranded" when used in reference to a nucleic acid substrate means that the substrate molecule exists primarily as a single strand of nucleic acid in contrast to a double-stranded substrate which exists as two strands of nucleic acid which are held together by inter-strand base pairing interactions.
As used herein, the phrase "non-amplified oligonucleotide detection assay"
refers to a detection assay configured to detect the presence or absence of a particular polymorphism (e.g., SNP, repeat sequence, etc.) in a target sequence (e.g. genomic DNA) that has not been amplified (e.g. by PCR), without creating copies of the target sequence. A
"non-amplified oligonucleotide detection assay" may, for example, amplify a signal used to indicate the presence or absence of a particular polymorphism in a target sequence, so long as the target sequence is not copied.
The term "sequence variation" as used herein refers to differences in nucleic acid sequence between two nucleic acids. For example, a wild-type structural gene and a mutant form of this wild-type structural gene may vary in sequence by the presence of single base substitutions and/or deletions or insertions of one or more nucleotides. These two forms of the structural gene are said to vary in sequence from one another. A second mutant form of the structural gene may exist. This second mutant form is said to vary in sequence from both the wild-type gene and the first mutant form of the gene.
The term "liberating" as used herein refers to the release of a nucleic acid fragment from a larger nucleic acid fragment, such as an oligonucleotide, by the action of, for example, a 5' nuclease such that the released fragment is no longer covalently attached to the remainder of the oligonucleotide.
The term "Km" as used herein refers to the Michaelis-Menten constant for an enzyme and is defined as the concentration of the specific substrate at which a given enzyme yields one-half its maximum velocity in an enzyme catalyzed reaction.
The term "nucleotide analog" as used herein refers to modified or non-naturally occurring nucleotides including but not limited to analogs that have altered stacking interactions such as 7-deaza purines (i.e., 7-deaza-dATP and 7-deaza-dGTP);

Schweitzer and E.T. Kool, J. Am. Chem. Soc., 1995, 117, 1863-1872);
"universal" bases such as 5-nitroindole and 3-nitropyrrole; and universal purines and pyrimidines (such as "K" and "P" nucleotides, respectively; P. Kong, et al., Nucleic Acids Res., 1989, 17, 10373-10383, P. Kong et al., Nucleic Acids Res., 1992, 20, 5149-5152). Nucleotide analogs include comprise modified forms of deoxyribonucleotides as well as ribonucleotides.
The term "polymorphic locus" is a locus present in a population that shows variation between members of the population (e.g.., the most common allele has a frequency of less than 0.95). In contrast, a "monomorphic locus" is a genetic locus at little or no variations seen between members of the population (generally taken to be a locus at which the most common allele exceeds a frequency of 0.95 in the gene pool of the population).
The term "microorganism" as used herein means an organism too small to be observed with the unaided eye and includes, but is not limited to bacteria, virus, protozoans, fungi, and ciliates.
The term "microbial gene sequences" refers to gene sequences derived from a microorganism.
The term "bacteria" refers to any bacterial species including eubacterial and archaebacterial species.
As used herein, the terms "high-risk HPV strains " or "high-risk HPV types"
refer to those strains of HPV that have been found in cancers (e.g., carcinomas). These HPV strains include HPV types 16, 18, 30, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 67, 68, 69 and 70.
The term "virus" refers to obligate, ultramicroscopic, intracellular parasites incapable of autonomous replication (i.e., replication requires the use of the host cell's machinery).
The term "multi-drug resistant" or multiple-drug resistant" refers to a microorganism that is resistant to more than one of the antibiotics or antimicrobial agents used in the treatment of said microorganism.
The term "sample" in the present specification and claims is used in its broadest sense. On the one hand it is meant to include a specimen or culture (e.g., microbiological cultures). On the other hand, it is meant to include both biological and environmental samples. A sample may include a specimen of synthetic origin.
Biological samples may be animal, including human, fluid, solid (e.g., stool) or tissue, as well as liquid and solid food and feed products and ingredients such as dairy items, vegetables, meat and meat by-products, and waste. Biological samples may be obtained from all of the various families of domestic animals, as well as feral or wild animals, including, but not limited to, such animals as ungulates, bear, fish, lagamorphs, rodents, etc.
Environmental samples include environmental material such as surface matter, soil, water and industrial samples, as well as samples obtained from food and dairy processing instruments, apparatus, equipment, utensils, disposable and non-disposable items. These examples are not to be construed as limiting the sample types applicable to the present invention.
The term "source of target nucleic acid" refers to any sample that contains nucleic acids (RNA or DNA). Particularly preferred sources of target nucleic acids are biological samples including, but not limited to blood, saliva, cerebral spinal fluid, pleural fluid, milk, lymph, sputum and semen.
An oligonucleotide is said to be present in "excess" relative to another oligonucleotide (or target nucleic acid sequence) if that oligonucleotide is present at a higher molar concentration that the other oligonucleotide (or target nucleic acid sequence).
When an oligonucleotide such as a probe oligonucleotide is present in a cleavage reaction in excess relative to the concentration of the complementary target nucleic acid sequence, the reaction may be used to indicate the amount of the target nucleic acid present. Typically, when present in excess, the probe oligonucleotide will be present at least a 100-fold molar excess; typically at least 1 pmole of each probe oligonucleotide would be used when the target nucleic acid sequence was present at about 10 fmoles or less.
A sample "suspected of containing" a first and a second target nucleic acid may contain either, both or neither target nucleic acid molecule.
The term "reactant" is used herein in its broadest sense. The reactant can comprise, for example, an enzymatic reactant, a chemical reactant or light (e.g., ultraviolet light, particularly short wavelength ultraviolet light is known to break oligonucleotide chains).
Any agent capable of reacting with an oligonucleotide to either shorten (i.e., cleave) or elongate the oligonucleotide is encompassed within the term "reactant."

As used herein, the term "purified" or "to purify" refers to the removal of contaminants from a sample. For example, recombinant CLEAVASE nucleases are expressed in bacterial host cells and the nucleases are purified by the removal of host cell proteins; the percent of these recombinant nucleases is thereby increased in the sample.
As used herein the term "portion" when in reference to a protein (as in "a portion of a given protein") refers to fragments of that protein. The fragments may range in size from four amino acid residues to the entire amino acid sequence minus one amino acid (e.g., 4, 5, 6, .., n-1).
The term "nucleic acid sequence" as used herein refers to an oligonucleotide, nucleotide or polynucleotide, and fragments or portions thereof, and to DNA or RNA of genomic or synthetic origin that may be single or double stranded, and represent the sense or antisense strand. Similarly, "amino acid sequence" as used herein refers to peptide or protein sequence.
As used herein, the terms "purified" or "substantially purified" refer to molecules, either nucleic or amino acid sequences, that are removed from their natural environment, isolated or separated, and are at least 60% free, preferably 75% free, and most preferably 90% free from other components with which they are naturally associated. An "isolated polynucleotide" or "isolated oligonucleotide" is therefore a substantially purified polynucleotide.
The term "continuous strand of nucleic acid" as used herein is means a strand of nucleic acid that has a continuous, covalently linked, backbone structure, without nicks or other disruptions. The disposition of the base portion of each nucleotide, whether base-paired, single-stranded or mismatched, is not an element in the definition of a continuous strand. The backbone of the continuous strand is not limited to the ribose-phosphate or deoxyribose-phosphate compositions that are found in naturally occurring, unmodified nucleic acids. A nucleic acid of the present invention may comprise modifications in the structure of the backbone, including but not limited to phosphorothioate residues, phosphonate residues, 2' substituted ribose residues (e.g., 2'-O-methyl ribose) and alternative sugar (e.g., arabinose) containing residues.
The term "continuous duplex" as used herein refers to a region of double stranded nucleic acid in which there is no disruption in the progression of basepairs within the duplex (i.e., the base pairs along the duplex are not distorted to accommodate a gap, bulge or mismatch with the confines of the region of continuous duplex). As used herein the term refers only to the arrangement of the basepairs within the duplex, without implication of continuity in the backbone portion of the nucleic acid strand. Duplex nucleic acids with uninterrupted basepairing, but with nicks in one or both strands are within the definition of a continuous duplex.
The term "duplex" refers to the state of nucleic acids in which the base portions of the nucleotides on one strand are bound through hydrogen bonding the their complementary bases arrayed on a 'second strand. The condition of being in a duplex form reflects on the state of the bases of a nucleic acid. By virtue of base pairing, the strands of nucleic acid also generally assume the tertiary structure of a double helix, having a major and a minor groove. The assumption of the helical form is implicit in the act of becoming duplexed.
The term "template" refers to a strand of nucleic acid on which a complementary copy is built from nucleoside triphosphates through the activity of a template-dependent nucleic acid polymerase. Within a duplex the template strand is, by convention, depicted and described as the "bottom" strand. Similarly, the non-template strand is often depicted and described as the "top" strand.

DESCRIPTION OF THE INVENTION
The present invention provides means for forming a nucleic acid cleavage structure that is dependent upon the presence of a target nucleic acid and cleaving the nucleic acid cleavage structure so as to release distinctive cleavage products. 5' nuclease activity, for example, is used to cleave the target-dependent cleavage structure and the resulting cleavage products are indicative of the presence of specific target nucleic acid sequences in the sample. When two strands of nucleic acid, or oligonucleotides, both hybridize to a target nucleic acid strand such that they form an overlapping invasive cleavage structure, as described below, invasive cleavage can occur. Through the interaction of a cleavage agent (e.g., a 5' nuclease) and the upstream oligonucleotide, the cleavage agent can be made to cleave the downstream oligonucleotide at an internal site in such a way that a distinctive fragment is produced. Such embodiments have been termed the INVADER assay (Third Wave Technologies) and are described in U.S. Patent Appl. Nos. 5,846,717, 5,985,557, 5,994,069, 6,001,567, and 6,090,543, WO 97/27214 WO 98/42873, Lyamichev et al., Nat, Biotech., 17:292 (1999), Hall et al., PNAS, USA, 97:8272 (2000) ), The INVADER assay detects hybridization of probes to a target by enzymatic cleavage of specific structures by structure specific enzymes (See, INVADER
assays, Third Wave Technologies; See e.g., U.S. Patent Nos. 5,846,717; 6,090,543; 6,001,567;
5,985,557;
6,090,543; 5,994,069; Lyamichev et al., Nat. Biotech., 17:292 (1999), Hall et al., PNAS, USA, 97:8272 (2000), W097/27214 and W098/42873, each of which is herein incorporated by reference in their entirety for all purposes).
The INVADER assay detects specific DNA and RNA sequences by using structure-specific enzymes (e.g. FEN endonucleases) to cleave a complex formed by the hybridization of overlapping oligonucleotide probes (See, e.g. Figure 1).
Elevated temperature and an excess of one of the probes enable multiple probes to be cleaved for each target sequence present without temperature cycling. In some embodiments, these cleaved probes then direct cleavage of a second labeled probe. The secondary probe oligonucleotide can be 5'-end labeled with fluorescein that is quenched by an internal dye.
Upon cleavage, the de-quenched fluorescein labeled product may be detected using a standard fluorescence plate reader.
The INVADER assay detects specific mutations and SNPs in unamplified, as well as amplified, RNA and DNA including genomic DNA. In the embodiments shown schematically in Figure 1, the INVADER assay uses two cascading steps (a primary and a secondary reaction) both to generate and then to amplify the target-specific signal. For convenience, the alleles in the following discussion are described as wild-type (WT) and mutant (MT), even though this terminology does not apply to all genetic variations. In the primary reaction (Figure 1, panel A), the WT primary probe and the INVADER
oligonucleotide hybridize in tandem to the target nucleic acid to form an overlapping structure. An unpaired "flap" is included on the 5' end of the WT primary probe. A
structure-specific enzyme (e.g. the CLEAVASE enzyme, Third Wave Technologies) recognizes the overlap and cleaves off the unpaired flap, releasing it as a target-specific product. In the secondary reaction, this cleaved product serves as an INVADER
oligonucleotide on the WT fluorescence resonance energy transfer (WT-FRET) probe to again create the structure recognized by the structure specific enzyme (panel A). When the two dyes on a single FRET probe are separated by cleavage (indicated by the arrow in Figure 1), a detectable fluorescent signal above background fluorescence is produced.
Consequently, cleavage of this second structure results in an increase in fluorescence, indicating the presence of the WT allele (or mutant allele if the assay is configured for the mutant allele to generate the detectable signal). In some embodiments, FRET
probes having different labels (e.g. resolvable by difference in emission or excitation wavelengths, or resolvable by time-resolved fluorescence detection) are provided for each allele or locus to be detected, such that the different alleles or loci can be detected in a single reaction. In such embodiments, the primary probe sets and the different FRET probes may be combined in a single assay, allowing comparison of the signals from each allele or locus in the same sample.
If the primary probe oligonucleotide and the target nucleotide sequence do not match perfectly at the cleavage site (e.g., as with the MT primary probe and the WT target, Figure 1, panel B), the overlapped structure does not form and cleavage is suppressed. The structure specific enzyme (e.g., CLEAVASE VIII enzyme, Third Wave Technologies) used cleaves the overlapped structure more efficiently (e.g. at least 340-fold) than the non-overlapping structure, allowing excellent discrimination of the alleles.
The probes turn over without temperature cycling to produce many signals per target (i.e., linear signal amplification). Similarly, each target-specific product can enable the cleavage of many FRET probes.
The primary INVADER assay reaction is directed against the target DNA (or RNA) being detected. The target DNA is the limiting component in the first invasive cleavage, since the INVADER and primary probe are supplied in molar excess. In the second invasive cleavage, it is the released flap that is limiting. When these two cleavage reactions are performed sequentially, the fluorescence signal from the composite reaction accumulates linearly with respect to the target DNA amount.
In certain embodiments, the INVADER assay, or other nucleotide detection assays, are performed with accessible site designed oligonucleotides and/or bridging oligonucleotides. Such methods, procedures and compositions are described in U.S. Pat.
6,194,149, W09850403, and W00198537.

In certain embodiments, the target nucleic acid sequence is amplified prior to detection (e.g. such that synthetic nucleic acid is generated). In some embodiments, the target nucleic acid comprises genomic DNA. In other embodiments, the target nucleic acid comprises synthetic DNA or RNA. In some preferred embodiments, synthetic DNA
within a sample is created using a purified polymerase. In some preferred embodiments, creation of synthetic DNA using a purified polymerase comprises the use of PCR. In other preferred embodiments, creation of synthetic DNA using a purified DNA polymerase, suitable for use with the methods of the present invention, comprises use of rolling circle amplification, (e.g., as in U.S. Pat. Nos. 6,210,884, 6,183,960 and 6,235,502 ).
In other preferred embodiments, creation of synthetic DNA

In these embodiments, amplification of DNA
such as genomic DNA is accomplished using a DNA polymerase, such as the highly processive 4) 29 polymerase (as described, e.g., in US Patent Nos. 5,198,543 and 5,001,050, each herein incorporated by reference in their entireties for all purposes) in combination with exonuclease-resistant random primers, such as hexamers.

In preferred embodiments, the kit further comprises instructions on how to perform the INVADER assay and specifically how to apply the INVADER detection assay to pooled samples from many individuals, or to "pooled" samples from many cells (e.g. from a biopsy sample) from a single subject.
The present invention further provides assays in which the target nucleic acid is reused or recycled during multiple rounds of hybridization with oligonucleotide probes and cleavage of the probes without the need to use temperature cycling (i.e., for periodic denaturation of target nucleic acid strands) or nucleic acid synthesis (i.e., for the polymerization-based displacement of target or probe nucleic acid strands).
When a cleavage reaction is run under conditions in which the probes are continuously replaced on the target strand (e.g. through probe-probe displacement or through an equilibrium between probe/target association and disassociation, or through a combination comprising these mechanisms, (The kinetics of oligonucleotide replacement. Luis P. Reynaldo, Alexander V.
Vologodskii, Bruce P. Neri and Victor I. Lyamichev. J. Mol. Biol. 97: 511-520 (2000)), multiple probes can hybridize to the same target, allowing multiple cleavages, and the generation of multiple cleavage products.
In some embodiments, the detection assays of the present invention are designed to detect one or more HPV sequences (See, e.g., Example 5). In some embodiments, multiple HPV sequences are detected in a single reaction (See, e.g., Example 5, Figure 9, reactions 10-658, 10-662, 10-677 and 10-682). In some preferred embodiments, a single oligonucleotide used in the detection assays is configured to hybridize to two or more HPV
sequences such that multiple HPV sequences can be detected with a single set of detection assay reagents (See, e.g., Example 5, Figure 9). In some embodiments, the oligonucleotides used in the detection assay are perfectly complementary to the intended HPV
target sequence. In other embodiments, the oligonucleotides contain one or more mismatches to the HPV target sequence of interest. Mismatches find multiple uses, including, but not limited to, the ability to reduce hybridization efficiency (which may be desired in some detection assay formats), the ability to add degeneracy (e.g., to detect two or more strains or variants), and the ability to compensate for sequence variation that may be in a sample. In some embodiments, where variation at a particular nucleotide position is identified in some members of a tested population, multiple oligonucleotides are provides that differ in sequence at the position so that each variant within the population is detected. Exemplary detection assay components for use in invasive cleavage assays are provided in the Example section below for certain preferred strains of HPV.

Example 1 Design of oligonucleotides to detect multiple HPV strains The objective of these experiments was to arrive at oligonucleotide designs suitable for use in INVADER assays comprising multiple target HPV strains. As a first step, HPV
DNA sequences were obtained from Genbank and aligned using SEQ WEB GAP and PRETTY programs (Accelrys, San Diego, CA). Only those regions of HPV that are reported to remain intact following chromosomal integration were analyzed to permit the assays to detect both integrated and non-integrated HPV sequences. Regions of suitable sequence conservation were chosen for select groups of strains. In this example, areas within the LCR, E6, and E7 genes were found to have considerable homology between HPV 18 and 59.
Candidate probe oligonucleotides were designed by searching for stretches of sequence comprising a limited number of mismatches between the two targets in either pair.
Designs were generated to several sequences on either the sense or antisense strands.
Suitable INVADER oligonucleotides were designed to accompany the respective probe oligonucleotide candidates. Initial INVADER oligonucleotide designs were selected to associate with only a single target, e.g. HPV 18, HPV 45, or HPV 59;
subsequent designs hybridize to more than one HPV strain. Candidate probe sets were then evaluated for two types of performance criteria: (1) signal generation at the chosen reaction temperature and (2) limit of detection, i.e. signal over background ratios at low levels of target DNA. Probe sets meeting desired performance cut-offs, in this case, optimal signal generation at 63 C
and LOD of 1000 copies of HPV DNA, were then selected for further evaluation.
Temperature optimization INVADER assays were performed in 96 well MJ Skirted microtiter plates. Plates were incubated using either an MJ Research PTC 100 Thermocycler or a ThermoHybaid PCR Express (Molecular Biology Instrumentation, Needham Heights, MA) and read with an Applied Biosystems CYTOFLUOR 4000 series multiwell plate reader.
INVADER assays to determine temperature optima of probe sets were set up by preparing primary and secondary reaction master mixes. In these experiments, two different INVADER oligonucleotides were tested in combination with a single probe oligonucleotide in each reaction. For example, in experiments designed to test probe sets for HPV 18 and 59, INVADER oligonucleotides for both HPV 18 and HPV 59 were included in each reaction along with a single probe oligonucleotide designed to associate with both strains of HPV. These reaction mixtures were tested separately on plasmid DNA comprising a portion of the HPV 18 (18c1) sequence (ATCC Catalog Number: 45152D) and a synthetic target comprising a portion of the HPV 59 sequence (SEQ ID NO: 42). Similarly, in experiments designed to detect HPV 45 and 59, INVADER oligonucleotides for both strains were included in each reaction along with the corresponding probe oligonucleotide and appropriate controls.
Master mixes containing primary reaction components were assembled for each set of temperature optimization reactions as follows. Reactions were carried out in parallel in microtiter plates.

All reactions were run in 5 duplicate. The targets were heat denatured at 95 C for 5 minutes, cooled to 20 C, and then aliquots of 4 l of the primary mix were added to each well. The microtiter plates were incubated for 2 hours in a ThermoHybaid thermocycler with a gradient heat block over a span of 10 degrees (i.e. reactions were run at 58, 58.3, 58.9, 59.8, 60.9, 62.2, 63.5, 64.9, 66.4, 67.3, 67.8, 68.1 C) and then returned to 20 C.

The settings used were: 485/20 run excitation/bandwidth and 530/25 nm emission/bandwidth for FAM dye detection. Unlike typical biplex INVADER reactions, because these assays include only a single probe molecule, only the single corresponding FRET
cassette is required. The instrument gain was set for each dye so that the No Target Blank produced between 50 - 150 Relative Fluorescence Units (RFUs).
Because the optimal gain setting can vary between instruments, gain is adjusted as needed to give the best signal/background ratio (sample raw signal divided by the No Target Control signal) or No Target Control sample readings of -100 RFUs.
Fluorescence microplate readers, that use a xenon lamp source generally produce higher RFUs. For directly reading the microplates, the probe height of, and how the plate is positioned in, the fluorescence microplate reader may need to be adjusted according to the manufacturer's recommendations.
The raw data that is generated by the device/instrument is used to measure the assay performance (real-time or endpoint mode). The equations below provide how FOZ
(Fold Over Zero), and other values are calculated. NTC in the equations below represents the signal from the No Target Control.
FOZ or Signal/No Target FOZDyeI = (RawSignalDyel/NTCDyeI) Candidate probe sets were selected based on the temperature profiles generated in these experiments. In particular, desirable probe sets exhibit temperature profiles on the two targets (e.g. HPV 18 and 59) tested together that exhibit similar trends with respect to increase in temperature, typically a bell shaped curve with its peak at the chosen reaction temperature, in this case 63 C. An additional desirable feature is that the peak not be precipitously lower plus or minus 1 or 2 degrees from 63 C. Fewer than 30% of the candidate probe sets yielded suitable temperature profiles.
In order to unify reaction conditions at a single reaction temperature, probe designs that gave rise to similar trends in response to temperature were chosen for further design optimization. Redesigned probes in which probe length was altered were tested.
Figure 2 shows the results of a temperature optimization experiment carried out with probe T3elb (SEQ ID NO:39) and INVADER oligonucleotides designed to detect HPV 18 (T3e4i) (SEQ
ID NO:40) and HPV 59 (T3e6i) (SEQ ID NO:41), respectively, on both the HPV 18 plasmid and HPV 59 (T3rT59) synthetic target (SEQ ID NO:42).
Similar temperature optimization and redesign procedures were carried out for all of the oligonucleotides presented in Figures 3 and 7.

Limit of detection (LOD) analysis In addition to optimizing for temperature profiles that follow the same general trends in response to temperature and do not present steep slopes in the immediate vicinity of the target reaction temperature, it is also desirable to optimize probe sets for analytical sensitivity or limit of detection (LOD). Measuring LOD is accomplished by conducting INVADER assays at a single reaction temperature while varying target concentration.
Reactions to determine LOD of temperature optimized probe sets were set up as follows. A dilution series of target DNAs (HPV 18 plasmid and synthetic target SEQ ID
NO: 42) was made in 10 ng/ l tRNA in dH2O; in the example presented here, target amounts per assay ranged from 125 copies/rxn to 8000 copies/rxn, doubling in each successive reaction. Aliquots of 15 l of diluted target or 10 ng/ l tRNA in dH2O for the no target controls were placed in appropriate wells of a microtiter plate and overlaid with 20 l of mineral oil. All reactions were run in quadruplicate. A master mix (MM) was made containing buffer, CLEAVASE X enzyme, MgC12, both INVADER oligonucleotides (SEQ
ID NOs: 40-41), primary probe T3elb (SEQ ID NO: 39) and FRET cassette oligonucleotides (SEQ ID NO: 63) as below.

Aliquots of 5 l of master mix were added and the reactions heated to 63 C for 4 hours. Upon completion, plates were removed to the CYTOFLUOR plate reader and analyzed as described above. Representative results are presented Figure 2. These results demonstrate that the designs tested in this experiment are suitable for the detection of as few as 250 copies of the corresponding HPV 18 and 59 sequences.

Example 2 Design of oligonucleotides to detect HPV 16 Candidate oligonucleotide sets having a primary probe and an INVADER
oligonucleotide were designed to detect regions in both HPV 16 and HPV 31 using the procedures described in the preceding examples. Designs were directed to the E7 gene of HPV. As in Example 1, different INVADER oligonucleotide sequences were tested in combination with a single probe sequence to find a probe set with optimal performance characteristics at the desired reaction temperature (63 C) and in terms of limit of detection (FOZ). Both temperature optimization experiments and LOD (FOZ) experiments were conducted as described above using 15 l of a 20 fM stock solution of HPV 16 plasmid (ATCC Catalog Number: 45113D). A total of 24 different INVADER
oligonucleotides were tested with SEQ ID NO: 1 (Alg3p); of these, one was chosen for use in assays to detect HPV 16: SEQ ID NO: 2 (A1gIOci), based on its temperature optimization profile and FOZ.

Co-detection of HPV 16 and a human genomic internal control sequence In some applications, it is desirable to co-detect an internal control sequence, for example in order to determine whether or not there are sample inhibition effects or operator errors. Oligonucleotide sets were designed to detect three different human genomic sequences and were tested in three different biplexed INVADER assays in combination with SEQ ID NOs: 1 and 2 to detect the HPV 16 plasmid. The human genomic regions were alpha actin (Genbank accession number NM_001100), the 3' untranslated region (UTR) of CFTR (Genbank accession number NM_000492), and hIGF (Genbank accession number AY260957). The oligonucleotides used for these designs were developed previously and optimized as described in the previous examples and were as follows: alpha actin probe SEQ ID NO: 64, INVADER oligo, SEQ ID NO: 65, FRET cassette 68; 3' UTR
CFTR probe SEQ ID NO: 66, INVADER oligo SEQ ID NO: 67, FRET cassette SEQ ID
NO: 68; hIGF probe SEQ ID NO: 69, INVADER oligo SEQ ID NO: 70, FRET cassette SEQ ID NO: 71.
A standard curve was generated using different amounts of HPV 16 plasmid against a constant amount of human genomic DNA. Reactions containing 0, 250, 500, 1000, 2500, 5000, 10,000, or 20,000 copies of the HPV 16 plasmid and either 100 ng (for hIGF and CFTR) or 250 ng (for alpha actin) human genomic DNA. DNA was isolated using the Gentra PUREGENE Autopure LS system (Gentra, Inc., Minneapolis, MN) or manual preparation methods. All other reaction components and detection were as described in the previous examples except that a second FRET oligo was used in each case (for hIGF, SEQ
ID NO: 71, red dye; for 3' UTR of CFTR and alpha actin, SEQ ID NO: 68, red dye). The results are presented in Figure 4 and indicate that all of the human genomic sequences tested were suitable for biplex detection in combination with varying levels of HPV

16 plasmid DNA. Furthermore, these experiments demonstrate that there is no apparent cross reactivity between the probe sets designed to detect HPV 16 and those designed to detect the human genomic sequences, as evidenced by both the unchanged signal generated using the IC
probes in the presence of variable amounts of HPV 16 DNA as well as by the lack of detectable signal generated using the HPV 16 probes in the absence of HPV 16 plasmid DNA.

Example 3 Effects of genomic DNA on detection of HPV 18 Experiments were carried out to assess the effect of exogenous human genomic DNA on detection of HPV 18. INVADER reactions were set up as follows. Serial dilutions of a synthetic HPV 18 target B1T18 (SEQ ID NO: 72) were made to result in numbers of target molecules as indicated in the X-axis of Figure 5 when 15 l were pipetted into the appropriate wells of a microtiter plate. A second set of serial dilutions was made incorporating human genomic DNA, purified as described in Example 2, into each dilution such that each reaction contained 1 .tg of human genomic DNA. No target controls contained 15 l of 1Ong/ l tRNA in distilled water. All reactions were run in duplicate. The target aliquots were overlaid with 20 l mineral oil and denatured at 95 C for 5 minutes then chilled to 20 C. A master mix containing INVADER reaction components was made as follows.
Reagent Stock Final Conc. # of reactions Volume Total Conc. /reaction volume INVADER oligo mixture 1 0.05 10 1 10 (SEQ ID NO: 73, 74, and 75) ( M) Primary probe (SEQ ID 10 0.5 1 10 NO: 76) B1b3 ( M) FRET Cassette (SEQ ID 10 0.25 0.5 5 NO: 63) (gM) MOPS (mM) 400 10 0.5 5 CLEAVASE X enzyme 50 2.5 1 10 (ng/ I) MgC12 (mM) 250 12.5 1 10 Total volume 5 50 Aliquots of 5 l of the master mix were added to each well. Reactions were incubated at 62 C for 4 hours and then read in the CYTOFLUOR as described above.

The results are presented in Figure 5 and demonstrate that the presence of 1 g of human genomic DNA does not exert a significant inhibitory effect on the INVADER assay designed to detect HPV 18 sequences.

Example 4 Simultaneous detection of multiple HPV strains in a single pooled reaction In some situations, it may prove desirable to combine detection of many HPV
strains in a single reaction vessel. For example, it may be desired to detect all high-risk HPV
strains or all low-risk strains in a single reaction mixture. In some cases, the output of a pooled reaction is a qualitative answer such as a positive result, indicating the presence of one or more HPV strains, or a negative result, indicating the absence of HPV.
Preferred oligonucleotide designs for pooling multiple INVADER reactions in a single well may possess the following characteristics:
The oligonucleotides do not interact with one another to promote excessive signal generation in the absence of a specific target. Background in the INVADER
assay may result from fragments of certain oligonucleotides that are an intrinsic component of some oligo synthesis mixtures. However, it is also possible for groups of different oligonucleotides to assume structures that are recognized and cleaved during the INVADER assay in the absence of target.

The oligonucleotides do not interact with one another to interfere significantly with signal generation in the presence of a specific target.

Performance of a given oligonucleotide set is comparable when tested in the pooled mixture and individually.

Pooled assays are created by combining probe and INVADER oligonucleotides in subcombinations and then assessing performance on each target by comparing signal generation and FOZ of the oligonucleotides in the pool to detection of that target in reactions containing only the probe and INVADER oligonucleotides designed to detect it.
In the event that a given oligonucleotide set is adversely affected by combination with other oligo sets in a single reaction vessel, e.g. generates excessive background or fails to generate the expected levels of target-specific signal, in some cases it is possible to swap in an alternative oligonucleotide set useful for determining the presence of the same HPV
strain. In other cases, it is possible to merely choose a different 5' arm for a particular probe oligonucleotide to reduce non-specific background generation or signal inhibition. In some cases, it is possible to detect the alternative strand of a particular target sequence, thereby altering the composition of the oligonucleotides and making them suitable for detection of the target in a pooled assay. In each case, the measure of a successfully performing assay is yield of statistically significant signal over background (FOZ) in the presence of the desired targets, e.g. 1.15 with t-test from neighbor < .05.
Ultimately, candidate oligonucleotide designs are pooled in various combinations and tested against a sample containing purified HPV DNA or partial HPV
sequences.
Optimally, samples of all HPV strains being tested are evaluated individually with the pooled oligonucleotide sets to confirm that target-specific signal is generated for each desired strain. Similarly, HPV negative samples or samples containing strains of HPV not desired to be tested (e.g. low risk strains, HPV 1, or other non-cervical strains) are also tested against the pools to confirm that they do not generate statistically significant FOZ.
Example 5 Detection of multiple HPV strains in cervical samples The methods and compositions of the present invention were used, as described in Example 4, to detect multiple strains of HPV in cervical samples.

INVADER oligonucleotide designs The INVADER assay was designed to detect high-risk HPV strains including 16, 18, 31,33,35,39 , 45, 51, 52, 56, 58, 59, 67, 68, and 70. Probe sets were combined into three pools based on HPV genetic phylogeny. Probe sets (e.g., probe and INVADER
oligonucleotides) were designed to hybridize to at least 2 different target regions for each HPV strain to accommodate for sequence polymorphisms and increase analytical sensitivity (See, e.g., Figure 6). Multiple HPV strains are detected by each of the three pools using the INVADER.assay (See, e.g., Figure 6). Probe and INVADER oligonucleotide sequences are listed in Figure 7. The probe and INVADER oligonucleotide sequences in Figure 10 may also be used. An internal control assay (alpha-actin) is included in each pool to measure the relative amount of genomic DNA levels in the samples and to provide a semi-quantitative method for HPV titer. The HPV specific probes in the A7 and A9 pools contained arm 1 (CGCGCCGAGG; SEQ ID NOS: 85, 88, 91, 94, 97, 101, 105, 108, 110, and 114) and utilized the corresponding FAM FRET cassette (Fam-TCT-Z28-AGCCGGTTTTCCGGCTGAGACCTCGGCGCG-hex, SEQ ID NO: 119). The HPV
specific probes in the A5/A6 pool contained arm AH9 (GGCAGTCTGGGAGT, SEQ ID
NO: 77, 79, 81, and 83) and utilized the FAM FRET cassette (Fam-TCT-Z28-AGCCGGTTTTCCGGCTGAGAACTCCCAGACTGCC-hex, SEQ ID NO: 120). The alpha-actin assay contained arm 3(ACGGACGCGGAG; SEQ ID NO: 117) and utilized the RED FRET cassette (Red-TCT-Z28-TCGGCCTTTTGGCCGAGAGACTCCGCGTCCGT-hex, SEQ ID NO. 121).

The settings used were: 485/535 nm excitation/emission for FAM dye detection, and 560/612 nm excitation/emission for RED dye detection. The instrument gain was set for each dye so that the No Target Blank produced between 1000 - 2000 Relative Fluorescence Units (RFUs). Because the optimal gain setting can vary between instruments, the gain was adjusted to provide the best signal/background ratio (e.g., sample raw signal divided by the No Target Control signal) or No Target Control sample readings.
For directly reading the microplates, the probe height of the microplate reader and the positioning of the plate was adjusted according to the manufacturer's recommendations.
The fluorescent signal from the Fam dye and the Red dye for the samples and No Target Control (NTC) was used to calculate fold over zero (FOZ) values as shown below.
FOZFam dye = (RawSignalFam/NTCFam) FOZRed = (RawSignalRed/NTCRed) The Fam FOZ corresponds to the signal from the HPV assays, and the RED FOZ
corresponds to the alpha-actin signal (See, e.g., Figure 9).

Results of INVADER assays for detection HPV in Cervical Specimens Quantification of DNA concentration in cervical samples may be achieved using various methods. For example, DNA concentration can be measured using the OliGreen ssDNA Quantitation kit (Molecular probes) or the alpha-actin INVADER assay (See, e.g., Figure 8). To determine the amount of DNA present in each sample using the INVADER
Assay, a control genomic DNA sample was serially diluted to generate a standard curve.
The alpha-actin INVADER assay standard curve was used to determine the amount of DNA
present in each sample using a linear regression analysis. Both methods are useful for determining concentrations of DNA in cervical samples. Since the signal from the alpha-actin INVADER assay can be detected in the same well as the HPV INVADER
assays, a separate quantitation step by OliGreen or measuring absorbance at 260 nm is not required.
The INVADER assay was used to detect the presence or absence of HPV (e.g., high-risk HPV strains) in cervical samples (See, e.g., Figure 9). Each sample was tested in three separate wells of a microtiter plate containing either the A5/A6, A7 or A9 INVADER
reaction mix. All wells contained the alpha-actin oligonucleotides and FRET
cassette.
Samples were considered to be HPV positive if the FAM FOZ values were greater than 3, HPV negative if the FAM FOZ values were less than 2, and equivocal if the FAM
FOZ

values were between 2 and 3. Of the 45 cervical samples tested, there were 21 positive samples, 23 negative samples, and 1 equivocal sample. Four of the samples were determined, using the methods of the present invention, to be co-infected with multiple HPV strains (See, e.g., Figure 9, samples 10-658, 10-662, 10-677 and 10-682).
