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
