RNA degradation is a serious problem and very hard to prevent since RNA is even degraded in -80ºC or liquid nitrogen storage. RNAStay™ Solution is a revolutionary reagent that can stabilize and protect RNA in tissues or cells at room temperature and thus allow users to isolate intact RNA or downstream storage of the treated tissue without the risk of RNA degradation. NAStay™ is an aqueous, non-toxic tissue and cell storage reagent that stabilizes and protects cellular RNA in intact, unfrozen tissue and cell samples. More conveniently, RNAStay™ eliminates the need to immediately process samples or to freeze samples in liquid nitrogen for later processing. Samples treated with RNAStay™ can be used with various downstream applications including mRNA and total RNA isolation kits such as phenol based kit or affinity binding isolation kit. Samples can be used for histology and immunocytochemistry or continued storage in liquid nitrogen for a long period without the risk of RNA degradation.

Rapid Protection Rapidly permeates tissues to stabilize and protect cellular RNA with immediate RNAse inactivation. Highly Quality No compromise in RNA quality following mRNA or total RNA isolation. Stable Stabilizes samples at room temperature for up to 1-4 weeks or indefinitely at -20ºC for archiving needs. Safe Aqueous non-toxic solution allows downstream tissue processing.
