[RI1000] RNAok™ RNase Inhibitor, (20 U/μl, 2000 U)

Call For Price



RNAok™ RNase Inhibitor is a recombinant mammalian RNase inhibitor that is purified by affinity chromatography from E. coli. This protein inhibits pancreatic-type ribonucleases, RNase A, B, and C by binding strongly to RNases in a noncompetitive mode at a 1:1 ratio. RNAok™ RNase Inhibitor does not inhibit eukaryotic RNases T1, T2, U1, U2, CL3 as well as prokaryotic RNases I and H. RNAok™ RNase Inhibitor is compatible with RT-PCR enzymes such as AMV, M-MLV and ExcelRT™ Reverse Transcriptase or Taq DNA polymerase. Extensive quality control tests ensure RNAok™ RNase Inhibitor is free of unwanted contaminants that can plague other commercially available preparations of RNase inhibitors.

RNAok™ RNase Inhibitor inhibits RNase A activity

Total HeLa RNA (1 µg) was incubated with 1U/µl of RNAok™ RNase Inhibitor and 0.4 ng RNase A for 30 min at 37°C. The result shows that RNAok™ RNase Inhibitor can protect RNA against 0.4 ng RNase A. (M: DM3100)
