Proteinase K (solution)

Description:
Proteinase K IVD (solution) is an enzyme for digesting proteins in biological samples supplied as a ready-to-use solution at a concentration of 20 mg/ml with an activity of ≥30 U/mg, intended for in vitro diagnostic use. Proteinase K (EC 3.4.21.64) is a broad-spectrum serine protease. The predominant site of cleavage is the peptide bond adjacent to the carboxyl group of aliphatic and aromatic amino acids with blocked alpha amino groups. It is a recombinant enzyme cloned from the fungus Engyodontium album and produced in Pichia pastoris. It is inactivated by diisopropyl fluorophosphate (DFP) or phenylmethanesulfonyl fluoride (PMSF). It is supplied as a solution that does not need to be dissolved before use.
