Proteinase K from the fungus Tritirachium album is a nonspecific serine protease that is useful for general digestion of proteins. Removal of endogenous nucleases during the preparation of DNA and RNA; preparation of tissue sections for in situ hybridization.
The virus consists of a protein shell and an internal nucleic acid. To amplify the nucleic acid by PCR, the shell protein must be destroyed first. The role of protease K is to break down the protein shell of the virus, releasing nucleic acid for easy detection.

3. Extract non protein components from tissues and degrade protein impurities. For example, the preparation of DNA vaccine；
4. Preparation of chromosome DNA by pulse electrophoresis；
5. Western blotting；
6. R&D and mass production of enzyme based glycated albumin reagents for in vitro diagnosis.
