RNases are ubiquitous, cause RNA degradation and can compromise RNA integrity. Recombinant RNasin® Inhibitor is a 50kDa protein that inhibits RNase A family and human placental RNases by noncovalently binding to RNases in a 1:1 ratio. Recombinant RNasin® Inhibitor does not inhibit RNase T1, S1 nuclease, RNase from Aspergillus, RNase H, RNase ONE™ Ribonuclease and enzymes for downstream applications such as GoScript™ Reverse Transcriptase, AMV/M-MLV reverse transcriptases, SP6, T7/T3 RNA polymerase, and Taq DNA polymerases. Learn more about our custom options for this product at: www....
