RNase Inhibitor is a recombinantly expressed, murine-derived RNase inhibitor produced using an E. coli expression system, with a molecular weight of 50 KDa. This RNase Inhibitor specifically binds to RNase A, B, and C in a non-competitive 1:1 ratio, effectively inhibiting the activity of all three RNases. The reaction is reversible; urea and sulfhydryl reagents can dissociate the complex, deactivate the inhibitor, and reinitiate RNase activity.
