Ribonuclease Inhibitor is a recombinant protein purified from E. coli strain carrying human placenta ribonuclease inhibitor gene. Ribonuclease Inhibitor specifically inhibits RNase A, RNase B, and RNase C. It is not effective against RNase 1, RNase T1, S1 nuclease, RNase H and aspergillus-originated RNase. It has no inhibition effect on DNA Polymerase, AMV, M-MLV, SP6, T7 and T3 RNA Polymerases.
