Ribonuclease inhibitor: Ribonuclease inhibitor (RNase inhibitor)
BIO BASIC INC. RNase Inhibitor is a highly purified, nuclease-free preparation. It is supplied at a concentration of 40,000units/ml, in a buffer containing 20mM HEPES-KOH (pH 7.6), 50mM KCl, 5mM DTT and 50% glycerol.
Each lot is rigorously tested and is guaranteed free of non-specific endonuclease, exonuclease, and RNase activity.
Placental RNase inhibitor is effective against RNase A and other eukaryotic RNase A-like proteins.
It does not inhibit RNA polymerases, DNA polymerases, RNase H, or RNase T1, and is therefore ideal for use in rtPCR reactions, in vitro transcription, or cDNA library construction.
One unit of this protein will inhibit 50% of the activity of 5 ng RNase A.
