Recombinant Ribonuclease Inhibitor

Takara Bio's Recombinant Ribonuclease Inhibitor is a recombinant protein that acts as a noncompetitive RNase inhibitor of RNase A, B and C. This RNase inhibitor is active over a wide pH range and in at least 1 mM DTT.

Unit Definition

One unit is defined as the amount of Recombinant Ribonuclease Inhibitor required to inhibit the activity of 5 ng of RNase A by 50%. Activity is determined as the ability to inhibit hydrolysis of cytidine 2,3'-cyclic monophosphate (cyclic CMP) by RNAse A.
