Proteinase K, from Tritirachium album, Thermo Scientific


Chemical Properties

Lyophilized powder
Storage & Sensitivity
Keep Cold.


  • 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.
  • Produces characteristic protein fragments used in enzyme/protein structure and function studies.


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 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.
