Description : Proteinase K is an endoproteolytic enzyme that cleaves peptide bonds at the carboxylic sides of aliphatic, aromatic or hydrophobic amino acids. Proteinase K is classified as a nonspecific serine protease. The smallest peptide to be hydrolysed is a tetrapeptide.

Applications : Proteinase K effectively digests native proteins. It can be used to inactivate DNases and RNases when isolating DNA and RNA from tissues or cells.

 

 

Usage Conditions:

• Proteinase K is active over a wide pH range—optimal activity between 6.5 and 9.5

• Under denaturing conditions—e.g., in the presence of SDS or urea

• In the presence of metal chelating agents—e.g., EDTA

• At high temperatures—optimum digestion temperature is 65°C

Unit Definition : One unit of the enzyme liberates folin-positive amino acids and peptides corresponding to 1μmol tyrosine in 1min at 37°C using denatured hemoglobin as substrate.

Quality Control : Tested for the absence of endo-, exodeoxyribonucleases and ribonucleases
