Proteinase K Powder（RNase-Free, DNase-Free） _ 10401ES DNA&RNA Extraction 146(16):5102-5114Proteinase K is a serine protease with wide cleavage activity, which can cleave the carboxyl terminal peptide bond of aliphatic and aromatic amino acids. Its relative molecular weight is about 29. 3 kDa. Proteinase K is widely used in the preparation of chromosomal DNA for pulse electrophoresis, Western blotting, and the removal of a nuclease from DNA and RNA preparation. Denaturant such as SDS (1%) can improve its activity. In addition, the common
