|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.
