Product Description RNase inhibitors are essential to protect RNA from RNase contamination. It inhibits the enzymatic activity of RNases by noncovalently binding to the active site. Murine RNase inhibitor is a recombinant RNase inhibitor of murine origin expressed and purified in E.coli. It specifically inactivates RNases such as RNase A, RNase B, and RNase C by binding covalently with RNase to form a 1:1 complex. Murine RNase Inhibitor is compatible with RNA synthesis, RT-PCR and other RNA-related reactions.

This product has been filed with the FDA Drug Master Files (DMF) and is assigned DMF #038031.
