General description
RNAlater ist ein wässriges, nicht toxisches Aufbewahrungsreagenz für Gewebe, das Gewebe schnell durchdringt, um die zelluläre RNA in situ in nicht eingefrorenen Proben zu stabilisieren und zu schützen. Gewebeschnitte werden entnommen und sofort zur Aufbewahrung in RNAlater eingetaucht. Dabei werden weder Qualität noch Quantität der RNA beeinträchtigt. RNAlater macht die sofortige Verarbeitung von Gewebeproben oder das Einfrieren von Proben in Flüssigstickstoff für die spätere Verarbeitung überflüssig. RNAlater konserviert RNA in Geweben bis zu 1 Tag bei 37 °C, bis zu 1 Woche bei 25 °C und bis zu 1 Monat bei 4 °C. Gewebe können auch langfristig bei -20 °C gelagert werden.
RNAlater wurde ausgiebig an verschiedenen Geweben von Wirbeltierarten getestet, darunter Gehirn, Herz, Niere, Milz, Leber, Hoden, Skelettmuskel, Fett, Lunge und Thymus. RNAlater wirkt zudem bei E. coli, Drosophila, Zellen von Gewebekulturen, Leukozyten und einigen Pflanzen.

Hello, is it possible to submerge samples (1mm3) of myocardium to RNA later, and then the next week into liquid nitrogen? As -80°C freezers are not available? Will it affect RNA stability and its modifications?
1 answer-
This application may be possible. However, it has not been specifically tested.

Does RNAlater stop transcription upon addition or only preserves the RNA from degradation by RNAases?
1 answer-
RNAlater™ is used to stabilize and protect RNA with immediate RNase inactivation. It works by denaturing proteins, including RNase. The use of RNAlater™ RNA Stabilization Solution for tissue storage does not affect the outcome of subsequent RNA expression analysis experiments compared to other processing methods. It is worth noting that proteins will be preserved in RNAlater™ however, the solution will denature the proteins. Therefore, the protein obtained from samples stored in it will still be suitable for applications such as western blotting or 2D gel electrophoresis, but not for applications that require native protein.
