General description
RNAlater est un réactif aqueux non toxique de stockage de tissus qui pénètre rapidement dans ceux-ci pour stabiliser et protéger l'ARN cellulaire in situ présent dans les échantillons décongelés. Les morceaux de tissu sont prélevés, puis immédiatement immergés dans RNAlater en vue de leur stockage, sans que cela ne compromette la qualité ou la quantité de l'ARN. Avec RNAlater, il n'est plus nécessaire de traiter immédiatement les échantillons tissulaires ou de les congeler dans de l'azote liquide en vue d'un usage ultérieur. RNAlater préserve l'ARN présent dans les tissus jusqu'à 1 journée à 37 °C, 1 semaine à 25 °C et 1 mois à 4 °C. Il est également possible de conserver les tissus à -20 °C sur le long terme.
RNAlater a largement été testé sur un certain nombre de tissus d'espèces vertébrées, notamment : cerveau, cœur, rein, rate, foie, testicule, muscle squelettique, graisse, poumon et thymus. RNAlater est également efficace avec E. coli, la drosophile, les cellules de culture tissulaire, les globules blancs et certaines plantes.

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.
