| Description | Source: Tritirachium album Description:Proteinase K is a highly active and stable endopeptidase used in a wide range of applications purified from the fungus T. album. It cleaves peptide bonds mainly following the carboxyl group of N-substituted hydrophobic aliphatic and aromatic amino acids(1) and is classified as a serine protease. Proteinase K is useful in purifying high molecular weight nucleic acids from cells and tissues (i.e. genomic DNA isolation from mouse tails) and in revealing protein structure and function. Tested User Friendly Properties: Molecular Weight: 28,900 Da Optimum pH: 4.0-12.5(1) Optimum Temperature: 65C(1) Working Concentration: 0.05 - 1 mg/ml Activators: Stimulated by 0.2 - 1% SDS or 1 - 4M urea(8) Inactivated by PMSF(1); Not inactivated by EGTA, thiol reagents or trypsin/chymotrypsin inhibitors(1) Form:Lyophilized powder Purity:Tested for contaminating ribonucleases and deoxyribonucleases. Shipping and Storage:Shipped on dry ice. Store dry at 4C. Unit Definition:One unit is the amount of enzyme that liberates folin positive amino acids and peptides corresponding to 1 mol tyrosine in 1 min at 37C using hemoglobin as substrate. Concentration:20 - 50 units/mg Applications:Used in the isolation of native, high molecular weight DNA and RNA. *Used as a general protease to inactivate DNases, RNases and to degrade proteins. *Specifically modifies cell surface proteins and glycoproteins for analysis of membrane structures for protein localization(5,6). *Produces characteristic protein fragments used in enzyme/protein structure and function studies(7). *Improves the cloning efficiency of PCR products. | |
