RNases are ubiquitous and can cause RNA degradation and compromise RNA integrity. Native and Recombinant RNasin® Inhibitors are 50kDa proteins that inhibit RNase A family and human placental RNases by noncovalently binding to RNases in a 1:1 ratio. For downstream applications such as GoScript™ Reverse Transcriptase, AMV/M-MLV reverse transcriptases, SP6, T7/T3 RNA polymerase, and Taq DNA polymerases, Recombinant RNasin® Inhibitor does not inhibit RNase T1, S1 nuclease, RNase from Aspergillus, RNase H, RNase ONE™ Ribonuclease and enzymes.

Unit Definition

One unit is defined as the amount of RNasin® Ribonuclease Inhibitor required to inhibit the activity of 5ng of ribonuclease A by 50%. Activity is measured by the inhibition of hydrolysis of cytidine 2,3´-cyclic monophosphate by ribonuclease A.
