||RNase Inhibitor, Mammalian specifically inhibits RNases A, B and C. It inhibits RNases by binding noncovalently in a 1:1 ratio with high affinity. It is not effective against RNase 1, RNase T1, S1 Nuclease, RNase H or RNase from Aspergillus. In addition, no inhibition of polymerase activity is observed when RNase Inhibitor is used with Taq DNA Polymerase, AMV or M-MuLV Reverse Transcriptases, or Phage RNA Polymerases (SP6, T7, or T3). The 50 kDa protein inhibits RNases by binding noncovalently in a 1:1 ratio with an association constant greater than 10^14.

||2000 U / 10000 U / 20000 U
||RNase Inhibitor, Mammalian (40,000 U/ml)
||One unit is defined as the amount of RNase Inhibitor, Mammalian required to inhibit the activity of 5ng of RNase A by 50%. Activity is measured by the inhibition of hydrolysis of cytidine 2', 3'-cyclic monophosphate by RNase A.
||For Research Use Only
||Store the RNase Inhibitor, Mammalian at -20°C. Please avoid repeated freeze-thaw cycles.
