Proteinase K is a serine protease that exhibits a very broad cleavage specificity. The Protein with a molecular weight 28.900 kD cleaves peptide bonds adjacent to the carboxylic group of aliphatic and aromatic amino acids. Proteinase K is not inactivated by chelating reagents such as EDTA or detergents such as SDS and is active over a wide range of pH (4 - 12.5). The enzyme belongs to the group of subtilisine-related serine proteases and is strongly inhibited by PMSF.

Proteinase K is offered as powder or in soluble form.

Customized amounts of Proteinase K Powder and Storage Buffer is available on request.
