Murine RNase Inhibitor is a recombinant mouse-derived RNase inhibitor expressed and purified in E. coli in a soluble form. It can extensively inhibit various RNases (RNase A, B, C). Murine RNase Inhibitor has undergone RT-PCR and RT-qPCR tests and is compatible with HiScript® II Reverse Transcriptase, HiScript® Reverse Transcriptase, M-MLV (RNaseH-) Reverse Transcriptase and various DNA Polymerases. Compared with human-derived RNase inhibitor, mouse-derived RNase inhibitor does not contain two cysteines that are very sensitive to oxidation in human protein, so it has higher antioxidant activity and is more suitable for experiments sensitive to high DTT (Such as qPCR).
