Verfahren zur Bestimmung der Zellverteilunz von Ribonukleinsäuren Die vorliegende Erfindung bezieht sich auf ein metachromatisches Verfahren zur Bestimmung der intrazellulären Verteilung der Ribonukleinsäuren in Tier- und Pflanzengeweben. Method for determining the cell distribution of ribonucleic acids The present invention relates to a metachromatic method of determination the intracellular distribution of ribonucleic acids in animal and plant tissues.
Die Kenntnis der Ribonukleinsäureverteilung in den Zellen, und die bei dieser Verteilung vorkommenden Veränderungen, sowohl bei der Mitose als auch bei verschiedenen tathologischen Prozesses, hat eine hervorragende Bedeutsamkeit für die Zellbioiogie.Knowledge of the ribonucleic acid distribution in cells, and the changes occurring in this distribution, both in mitosis and in various process of tathology, has a great significance for cell biology.
Zur Bestimmung der Ribonukleinsäureverteilung sind bereib zahlreiche Verfahren bekannt. Es gibt, z. B.There are numerous available for determining the ribonucleic acid distribution Procedure known. There are e.g. B.
metachtomatische Methoden, welche die Eigenschaft des Toluidinblaus und des Azurs I und II benutzen, rotfarbige Verbindungen mit der Ribonukleinsäure und Fettstoffen zu bilden; diese Methoden sind aber unspezifisch und unselektiv. Man benutzt noch zum selben Zwecke weiterhin die Eigenschaften des Pyronins, die riboneukleinischen Zellstrukturen rot zu färben; diese Methode gestattet jedoch den Nachweis der chromosomischen Ribonukleinsäure nicht und gibt keine Auskunft über die Nukleolstruktur.metachomatic methods showing the property of toluidine blue and Azure I and II use red-colored compounds with ribonucleic acid and fatty substances to build; however, these methods are unspecific and unselective. The properties of the are still used for the same purpose Pyronins to stain ribonuclein cell structures red; this method allowed however, the detection of the chromosomic ribonucleic acid does not provide any information about the nucleolar structure.
Ebenfalls kennt man noch elektromikroskopische und autoradiographische Methoden, bei welchen man das tritiumhaltige tridin (H3) als Vorgänger in der Ribonukleinsäurebiosynthese benutzt, beide Verfahren setzen jedoch eine teuere Apparatur voraus und sind schwierig-durchzufiüiren.Electromicroscopic and autoradiographic ones are also known Methods in which the tritiated tridine (H3) is used as a precursor in ribonucleic acid biosynthesis are used, but both methods require expensive equipment and are difficult to carry out.
Die vorliegende Erfindung beseitigt die Nachteile der erwähnten Methoden dadurch,.dass die Schnitte von fixierten Tier-und Pflanzengeweben mit basischen Farbstoffen aus der Thioningruppe in hydroalkoholischer 0,005 bis 0,01 gew.°%iger Pufferlösung gefärbt, mit Methanol, welches~0,8 Vol.% Salzsäure enthält und nachher mit einer hydroalkoholischen 0,5 bis 1gew.0/ igen Essiguranyllösung behandelt werden.The present invention overcomes the disadvantages of the aforementioned methods thereby, that the sections of fixed animal and plant tissues with basic Dyes from the thionine group in hydroalcoholic 0.005 to 0.01% by weight Buffer solution colored, with methanol, which contains ~ 0.8% by volume of hydrochloric acid and afterwards be treated with a hydroalcoholic 0.5 to 1% by weight aceticuranyl solution.
Das Verfahren stützt sich auf die Eigenschaft der basischen Farbstoffe aus der Ehioningruppe und besonders des 0-Toluidinblaus, alle ribonukleinischen ZellstruXturen auf vorher mit hydrochlorischem Methanol behandelten miktoskopischen Präparaten rot zu färben, wonach eine Uranylionenbehandiung'durchgeführt wird.The process is based on the property of basic dyes from the ehionin group and especially the 0-toluidine blue, all ribonucleinic Cell structures on microscopic microscopes previously treated with hydrochloric methanol To color preparations red, after which a uranyl ion treatment is carried out.
Die Spiazifität -des Verfahrens besteht darin, dass durch Behandlung -der Tier- -oder Pflanzengewebeschnitte mit hydrochlorischem methanol die Gruppierungen -COOH durch Methylierung) und -0-SODH (durch Methan-olyse) aus den sauren Poly-~ sacchariden blockiert werden, wodurch verhindert wird, dass diese an metachromatischen Reaktionen teilnehmen.The practicality of the procedure is that through treatment -the animal or plant tissue sections with hydrochloric methanol the groupings -COOH by methylation) and -0-SODH (by methanolysis) from the acidic poly- ~ saccharides are blocked, which prevents them from becoming metachromatic Reactions to participate.
Durch die Anwendung des Farbstoffs in hydroalkoholischer Lösung wi-rd weiterbin die Möglichkeit beseitigt, dass die sauren Zellfettstoffe metachromatisch -reagieren, da auch die geringsten Alkoholmengen die vondiesen Fettstoffen gebildete Metachromasie vernichten. Durch Verwendung der Uranylionenpräparate wird bei den Arbeitsbedingungen dieses Verfahrens gewährleistet, dass nur die Zellribonukleinsäure- wegen der in ihrem Molekä: enthaltenen Phosphatgruppierungen - - beständige metachromatische Komplexe, d. h. rotfarbige Komplexe, mit dem Farbstoff -bildet, während die anderen nicht ribonukleischen-Zellstrukture#sich orthochromatisch, d. d. h. hellblau, färben.By using the dye in a hydroalcoholic solution wi-rd Furthermore, the possibility is eliminated that the acidic cell fat substances are metachromatic -react, since even the smallest amounts of alcohol are those formed by these fatty substances Destroy metachromasia. By using the uranyl ion preparations, the The working conditions of this process ensure that only the cell ribonucleic acid because of the phosphate groups contained in their molecule - - permanent metachromatic Complexes, d. H. red-colored complexes, with the dye -forms, while the other non-ribonuclear cell structure # is orthochromatic, d. d. H. light blue, color.
