INVENT OR AARON E. FREEMAN By a ATTORNEY United States Patent 3,649,464 ASSAY AND CULTURE TRAY Aaron E. Freeman, Rockville, Md., assignor to Microbiological Associates, Inc., Bethesda, Md. Filed Dec. 5, 1969, Ser. No. 882,493 Int. Cl. C12k 1/00 U.S. Cl. 195-140 15 Claims ABSTRACT OF THE DISCLOSURE A plate or tray suitable for assay and cell and tissue culture on a miniature scale comprises a transparent base member made of plastic and having extending upward therefrom a plurality of parallel rows of open top cylindrical wells spaced apart from each other a suicient distance to avoid cross-contamination, an integral peripheral upstanding wall terminating in a flange provided with a seat adapted to receive and sercure a lid having a downwardly extending wall adapted to engage the flange portion of the plate, which lid may include a plurality of parallel rows of downwardly extending well seals positioned to engage the mouth portions of the wells to form closures therefor.
BACKGROUND OF THE INVENTION The rapid expansion of cell and tissue culture, particularly in the iield of virology, has made necessary the processing of large numbers of individual cultures by macrotechniques, employing standard size Petri dishes and other culture vessels. The need for subsequent virus isolation, titration, and assay tests and the like, has involved the handling and manipulation of large numbers of culture vessels and the transfer of substantial volumes of media with attendant space requirements, and hazards of spillage and contamination.
Efforts have been made by virologists and others engaged in cell and tissue culture to utilize for growth, virus assay, neutralization and toxicity tests and the like, the currently available miniature titration or assay plates. These plates are designed for complement-fixation and other serological tests and have proved to be poorly adaptable and generally inadequate for cell and tissue culture purposes. Such assay or titration plates customarily cornprise a one piece molded plastic shell including a plurality of parallel rows of uniformly arranged cups which depend downwardly from a top wall which contains the open upper ends of the cups, tangentially disposed to each other, the closed lower ends being individually formed at the bottoms of the respective cups. When it is attempted to utilize such assay plates for cell and tissue culture purposes, one drawback is the possible cross-contamination of viruses, reagents and cells from one cup or well to another because of the arrangement of the cups whereby the fact that their openings are flush with the top wall surface permits any spillage to llow from one cup into another, which spillage may even result in possible contamination of an entire incubator where the plate is being used in an incubator.
The commercially available miniature titration plates employ a standard type of tape sealing system to cover the well openings and when an eifort is made to use such plates for cell or tissue culture purposes, the tape presents the danger of causing cross-contamination through a mechanical action.
Accordingly, there has existed a need for a cell and tissue culture and assay plate, particularly adapted for cell and tissue culture and attendant assays on a miniature scale and which would be free from the drawbacks of other types of plates not designed specifically for cell and tissue culture purposes.
GENERAL DESCRIPTION OF THE INVENTION In accordance with the present invention, there is provided a novel cell and tissue culture and assay plate, capable of multiple culturing or assaying on a miniature scale, together with a special lid or cover therefor.
The miniature plate of the invention comprises a transparent integral molded base from which there extend upward a multiplicity of small cups or wells arranged in rows, which are capable of functioning as culture vessels for cell or tissue culture, or as cups for microassay work. The outer walls of the cups or wells protrude upward, and are spaced apart from each other, and are not adjoined by an upper wall surface, thereby eliminating the possibility of spillage flowing from one well to another, by reason of the troughs made between adjacent cups or wells. This serves to prevent cross-contamination when the cups are employed for cell or tissue culture Work. The plate is also provided with an upstanding peripheral wall which forms a trough with the bottom of the plate and serves to prevent external spillage.
These and other novel features and advantages of the plate of the invention will be better understood by reference the accompanying drawings, in which:
FIG. 1 is a top plan View of the miniculture plate showing the arrangement of the cups or wells;
FIG. 2 is a section taken through the plate of FIG. l, taken along the line 2 2 of FIG. 1;
FIG. 3 is a top plan View of a particular form of the lid or cover;
FIG. 4 is a cross-sectional view of the lid of FIG. 3 taken along the line 4 4;
FIG. 5 is a cross-sectional view of another form of the lid or cover provided with well-sealing means;
FIG. 6 is a view in perspective of a type of well sealing means;
FIG. 7 is a cross-sectional view showing the interrelationship of two stacked trays;
FIG. 8 is a cross-sectional view showing the interrelationship of a tray covered with a lid and a second tray superimposed thereon; and
FIG. 9 is a View in perspective of the bottom of a tray showing the peripheral bead thereon.
Referring now to the drawings, IFIG. 1 illustrates a presently preferred embodiment of the in'vention, in which the miniature culture or assay plate is shovm generally at 10, and includes a bottom tray 11 from which there extend upward `a plurality of rows of cups or wells 12, each having a thin `wall 13. These cup walls are spaced apart from each other to form troughs between them and to avoid any danger of cross-contamination of the individual cups or wells by reason of spillage or overflow of the well contents. The cups are of equal depth and diameter. Thus, for example, the typical dimension of a well is ka wall height of approximately l0 mm., the wall having an inside diameter of approximately 7.5 mm. The space between adjacent outside Wall surfaces is Iafbout 1 mm. which will ordinarily suffice to avoid the cross-contamination referred to above. The cups may be of any desired shape, but are preferably cylindrical.
The plate is preferably integrally molded of `a suitable transparent plastic material, for example a vinyl resin material, or methyl methacrylate type material, which exhibits high mechanical strength, light weight, is readily cleaned if the plate is to be re-used, and which is suiciently inexpensive so that the plate (and cover) may be treated as disposable.
In the embodiment shown in FIG. 1, the general dimensions of the plate or tray will typically comprise, for example, an over-all length of about 124 mm., and a width of about 80 mm. One corner of the plate is provided with a cut-oil beveled edge 14. This permits design of the lid to have the same configuration as the plate itself, and forces the user to replace the lid in its original position, eliminating cntamination and other difficulties which might arise from replacing the lid in the wrong position.
In the preferred embodiment shown in FIG. l, there are 12 rows of cups or wells, each row containing 8 cups, providing a total of 96. However, it will be understood that the number of cups and their arrangement may be varied yas circumstances require. The trav 11 may be, for example, about 3 mm. thick.
Referring to FIG. 2, there extends peripherally around the edge of the tray 11 an upstanding wall 15, which is molded integrally therewith, the main portion of which wall advantageously has an over-all height equal to approximately one-half the height of the cups or wells, i.e. about 5 mm., but this is not critical. The wall terminates in an integral iiange 16, having a `seat 17 formed by an extension of the Awall which serves to seat and secure the lid 20, as described below.
Por purposes of tray stacking, the tray 11 of the plate is provided with a downwardly extending peripheral bead or lug 18, which is adapted to tit around and encompass the outer limit of the array of wells 19 so that when one tray is stacked on top of another without the lid 20, the upper tray is anchored and cannot slide off. The bead 18, in addition to permitting stacking of the plates, also serves to prevent the bottom of the plate from being scratched when laid on a surface, thus preserving its optical qualities. The arrangement of 4bead 18 will be more clearly understood by reference to FIG. 9.
The microculture plate of the invention may be provided with a suitable lid or cover, the basic version of which is illustrated in FIGS. 3 and 4. The lid 20 is advantageously made of transparent plastic material, and is integrally molded. It includes a substantially at wall 21, which merges into a downwardly extending peripheral wall 22 as shown in FIGS. 4 and 5. The lid is so designed that the wall height is sufficient, when the lid is seated over the miniculture plate 10, to provide a clearance between t-he tops 19 of the wells 12 and the lower surface 21a of the lid wall 21. Typically, 'such clearance may be, for example, about 2 to 3 mm. The lid has a conliguration matching that of the plate itself, that is, it is provided with the cut-off or bevel corner 23, to engage the plate in a single position. In the embodiment shown in FIGS. 3 and 4, the lid wall terminates in a ange portion 24, as shown in TIG. 4, having an inner lug 25, to engage the edge of the ange 16 and the seat 17 at the upper end of the plate Wall 15. This minimizes possible contamination.
This tray stacking principle is illustrated more clearly in FIG. 7, showing the inter-relationship of the bead 18 and the wells 19, with respect to the wall ange portions 16 and 17, the function of the bead 18 here being to prevent lateral sliding of the upper tray. When trays are thus stacked, the wells can be sealed with the sealing strip illustrated in FIG. 6, and described below.
-Extending upward from the lid wall 21 is a peripheral lug 26 which serves to engage the downwardly extending bead 18 of the plate 10, when a set of plates and lids is stacked. This principle is illustrated in FIG. 8. When the lid is applied to the tray, the outer edge of the lid peripheral wall 22 does not extend beyond the edge of flange 16 of the tray, so that the protruding iiange portion 16 of the tray permits grasping and lifting of the tray without the danger of grasping the lid and having the tray drop ott. I
In a modied version of the lid shown in FIG. 5, there are provided integrally molded well seals 27, which extend downwardly from the lid wall 21, in a number matching the number of cups or wells, and positioned so as to engage the mouth portion 19 of the wells by penetrating into the well openings. For this purpose the well seal walls 28 are tapered so that they wedge into the well, providing a positive seal.
The form of well seal shown in FIG. 6 is intended to be used as the sealing means for a given row of wells, or to be used in conjunction with the form of lid shown in FIG. 4. It comprises ya strip 30 of a transparent plastic material having integrally molded therein a set of 12 or 8 individual well seals 31 which are adapted to extend into the mouths 19 of the individual wells. The well seals 31 advantageously have tapering walls of the type described in connection with the embodiment of FIG. 5. The strip may be utilized so that the S rows of 12 wells can be sealed individually, or conversely, if an 8-seal strip is used, so that the 12 rows of 8 each can be thus sealed. In this way the user can remoive the sealing strip from one row at a time without unsealing the remaining 7 or 11 rows of wells. Tab 32 forming one end of strip 30 is provided for this purpose.
