I am having trouble performing PCR amplification after DNA isolation with RNAlater-treated samples. Does RNAlater have an impact on downstream PCR applications?

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.

What is the difference between RNAlater Stabilization Solution and RNaseOUT Recombinant Ribonuclease Inhibitor? When do I use one over the other?

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.
