Proteinase K is a highly active and stable serine protease with low cleavage specificity and an extremely broad range of proteolytic specificity. This protein, with a molecular weight of 28.9 kDa, can cleave peptide bonds near the carboxyl groups of aliphatic and aromatic amino acids. Widely used in molecular biology experiments, Proteinase K primarily functions to degrade proteins by hydrolyzing peptide bonds, and is particularly adept at breaking down denatured or cross-linked proteins. It plays a crucial role in processes such as DNA/RNA extraction, cell lysis, and removal of nuclease contamination.

Jena Bioscience's Proteinase K features excellent performance and high purity, making it an ideal choice for protein digestion and nucleic acid isolation. Meanwhile, it is available in ready-to-use solution and versatile powder formulations.
