产品说明
DetailsProteinase 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°CUnit 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
