Proteinase K CAS NO 39450-01-6 Lyophilized Powder from Tritirachium album limber. CAS No. 39450-01-6 Molecular Formula: C29H27N2O12P Molecular Weight: 626.504641 EINECS NO. :254-457-8 Other name: CHLOROM; IUB:3.4.21.14; IUB: 3.4.21.64; EC 3.4.21.14; EC 3.4.21.64; ENDOPEPTIDASE K; 3.4.21.14; PROTEINASE K. Protease k is a highly active protease of the subtilisin class, used for the general degradation of proteins in biological samples. It is purified from Tritirachium album limber. Protease K is a serine protease with broad cleavage activity. It cleaves the carboxy terminal peptide bond of aliphatic amino acid and aromatic amino acid. This enzyme is purified to remove RNase and DNase activities. Since proteinase K is stable in urea and SDS, it also has the ability to degrade natural proteins. Application: 1.Gene Diagnostic Kit 2.Genomic DNA extraction kit 3.RNA extraction kit removes nucleases from DNA and RNA preparation 4.Extract non-protein components from tissues to degrade protein-containing impurities-such as preparation of DNA vaccines and heparin 5.Preparation of chromosomal DNA for pulse electrophoresis 6.Western Blot 7.The general working concentration of proteinase K is 50-100ug / ml Proteinase K Source: Tritirachium album limber Appearance: white lyophilized powder Specific activity: > 30 U / mg protein (measured 33-36U / mg, subject to the current batch of COA). Molecular weight: 29kDa (SDS-PAGE) Definition of activity unit: at 37 and pH 7.5, the substrate casein can be hydrolyzed to produce 1 �¼mol of tyrosine eggs per minute The amount of white enzyme K is defined as one unit (U). Residue of DNase: Digested with �» DNA as the substrate for more than 6 hours at 37 , no deoxyribonuclease activity was detected. RNase residue: Digested at 25 for more than 16 hours, no ribonuclease activity was detected. Inactivation method: adding benzenesulfonyl chloride (PMSF) or diisopropyl fluorophosphoric acid (DFIP) inhibitor to the reaction system Alive, incubation at 65 for 10-15min can partially inactivate. Packing: 100g / bottle; 500g / bottle; 1Kg / bottle Storage: The dry powder state can be stored for a long time under the condition of -20 .
