PR1MA™ RNase Inhibitor

PR1MA™ RNase Inhibitor (RI) is a 50 kDa protein that specifically inhibits RNases A, B, and C by binding noncovalently in a 1:1 ratio at high affinity. It can be used in isothermal amplification and molecular diagnostic assays, cDNA synthesis, and other applications where RNA stability is important. It is ineffective against RNase1, T1, S1 Nuclease, or RNase H. It has no inhibition of polymerase activity when used with Taq DNA polymerase, AMV, M-MuLV, HIV reverse transcriptases, or phage RNA polymerases.
