Proteinase K is a non-specific serine protease with a very high specific activity. It has been used for isolation of mRNA, high molecular weight DNA and inactivation of other enzymatic activities. Proteinase K is active with or without the presence of SDS, EDTA and chaotropic salts.

Proteinase K is a broad-spectrum serine protease for general digestion of proteins in biological samples. The enzyme is free of RNase and DNase activities. The recommended working concentration for Proteinase K is 50 - 100 µg/mL in the majority of applications.
