IBI Scientific Proteinase K Powder, 100 mg

IBI Scientific Proteinase K Powder, 100 mg Net Content, Lyophilized Powder Form, White, -20 deg C, 28.9 Kda Molecular Weight. Recombinant proteinase K powder, originally isolated from the mold Engyodontium album, is a serine protease with broad substrate specificity and relatively high proteolytic activity. It preferentially cleaves ester and peptide bonds adjacent to the C-termini of hydrophobic, aliphatic or aromatic amino acids. IBI Scientific recombinant proteinase K powder is highly pure, determined by SDS-PAGE to be 95%. High purity, sterility, no bio-burden and no presence of DNase, RNase, DNA and RNA contaminants. By using absorbance A275 as the vertical axis and different concentrations of a tyrosine as the horizontal axis the enzymatic activity was calculated to >30 U/mg. IBI Scientific recombinant proteinase K powder is expressed in pichia pastoris, purified and lyophilized - IBI (Additional Shipping And Hazmat May Apply)
