Usage
This inhibitor exhibits broad-spectrum RNase inhibitory properties, including RNase A, RNase B, RNase C and human placental RNase. Does not inhibit RNase T1, S1 nuclease, RNase from Aspergillus, and RNase H. The 50kDa protein exerts its inhibitory effect by noncovalently binding to RNases in a 1:1 ratio. This inhibitor can be applied to a reverse transcriptase reaction.
