RNase Inhibitor completely inhibits the activity of RNases A, B and C by non-covalent binding. It binds the RNases in a 1:1 ratio with an association constant of approx. 1014 M. It does not inhibit the RNases I, T1, T2, H, U1, U2 and CL3.
RNase inhibitor should be applied in a working concentration of 40 units (1 μl) per 50 μl reaction volume. The application of RNase inhibitor is recommended for:
