Cat#:RP-5225H;Product Name:Recombinant Human PROK Tritirachium album;Synonym:Proteinase K (EC:3.4.21.64), Endopeptidase K, Tritirachium alkaline proteinase, PROK.;Description:Recombinant Tritirachium album Proteinase-K expressed in yeast containing 285 amino acids having a Mw of 29.3 kDa is purified by standard chromatography techniques.;Source:Yeast;Purity:Greater than 99% as determined by SDS-PAGE.;Bioactivity:34 Units/mg protein. One unit is defined as the amount of enzyme that will hydrolyze urea-denatured hemoglobin to produce color equivalent to 1.0 mol tyrosine per min at 37°C, pH 7.5 (color by Folin-Ciocalteu reagent).;Formulation:The Proteinase-K was lyophilized without any additives.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Proteinase-K in 20mM Tris-HCl (pH 7.4~8.0), 1mM CaCl2, 50% glycerol not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Recombinant Proteinase-K although stable at room temp for 1 week, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
