RNase Inhibitor, Human Placenta, specifically inhibits RNases A, B and C.

  • Isolated from a recombinant source

  • Inhibits common eukaryotic RNases

  • Compatible with Taq DNA Polymerase, AMV or M-MuLV Reverse Transcriptases

  • Active over a broad pH range (pH 5-8)

  • Tested for the absence of DNases and RNases

RNase Inhibitor, Human Placenta is a recombinant human placental protein which specifically inhibits ribonucleases (RNases) A, B and C (1). 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, Human Placenta 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 1014 (2).
