The Murine RNase inhibitor is a soluble mouse-source recombinant protein expressed in E.coli. It can inhibit all kinds of Rnase (RNase A, B, and C). The Murine RNase inhibitor is compatible with the M-MLV (H-) Reverse Transcriptase (ACE Biolabs, EP2001) and any kinds of DNA Polymerases. Compared with the human-source RNase inhibitor, the Murine RNase inhibitor doesn’t contain the two Cys that is sensitive to oxidation, and therefore has a higher antioxidant activity and is more suitable for high-DTT-sensitive experiments (i.e. qPCR).
