RNaseOUT Recombinant Ribonuclease Inhibitor maintains full activity from 4 degrees C to 55 degrees C. Activity decreases at higher temperatures, and heating to 65 degrees C inactivates the enzyme. Under prolonged reaction conditions, the inhibitor remains active for at least 96 hours at 4 degrees C and 25 degrees C, 24 hours at 37 degrees C, and up to 6 hours at 50 degrees C.

RNAlater should not impact downstream PCR amplification as long as the sample has been properly cleaned before proceeding with DNA isolation, as stated in the RNAlater Stabilization Solution manual (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/7020M.pdf) on page 7.

RNAlater Stabilization Solution stabilizes and protects cellular RNA in intact, unfrozen tissue samples, eliminating the need to immediately process tissue samples or to freeze samples in liquid nitrogen for later processing. In other words, it is an RNA preserving reagent.

RNaseOUT Recombinant Ribonuclease Inhibitor is a potent non-competitive inhibitor of pancreatic-type ribonucleases such as RNase A, and is used to avoid RNA degradation in a variety of applications such as cDNA synthesis, RT-PCR, and in vitro transcription and translation. RNAseOUT inhibits RNase A, RNAse B, and RNAse C. In other words, RNaseOUT Recombinant Ribonuclease Inhibitor is mainly used in an assay to prevent RNA degradation.
