Recombinant Proteinase K, PCR grade
Recombinant Proteinase K, PCR and molecular biology grade, based on sequence of enzyme from fungus Tritirachium Album Limber, expressed and purified from recombinant source
EC 184.108.40.206 - CAS# 39450-01 - M.W. 29.3 kDA
Proteinase k from Tritirachium Album Limber and its recombinant variants are the most used enzyme for general digestion of proteins. It got its name from its unique ability to digest keratin, such as hair or nails. An essential lab reagent, proteinase K is a broad spectrum serine protease enzyme. It's a member of the S8 (subcilisin) family of proteases. Proteinase K is also known under the names of protease K, endopeptidase K, and Tritirachium alkaline proteinase.
Proteinase K digests native proteins by clearing peptide bonds adjacent to the caroboxyl group of aromatic and aliphatic amino acids with blocked alpha amino groups. It is activated by Ca++ ions, and it is stable in the presence of chelating agents.
Proteinase K is commonly used for its broad specificity in sample digestion/lysis. It's main application is in isolation of high quality genomic DNA and RNA out of microbial and mammalian samples. During the process of tissue lysis or homogenization, proteinase K protects nucleic acids by rapidly degrading RNAses and DNAses enzymes, and as such is essential component of many molecular diagnostics, forensics and life sciences protocols and kits.
