Proteinase K is a subtilisin-like endolytic protease that is isolated from the saprophytic fungus Tritirachium album. It has a high activity that is stable across a wide range of pH and temperature conditions and is suited to short digestion times. The activity of proteinase K is increased at elevated temperatures up to 65° C. Calcium is not essential to the function of proteinase K. Therefore, EDTA and other chelating agents do not interfere with the activity and may be used alongside proteinase K to inactivate calcium-dependent nucleases in DNA and RNA preparation.
500ul of 0.5mg/ml Protease suspended in 10 mM Tris-HCl, 1 mM EDTA, pH 7.5.
