This enzyme has been widely exhibits substrate specificity and degrades many proteins in the native state. Proteinase K is inhibited by serine protease inhibitors such as phenylmethylsulfonyl fluoride. This enzyme activity is unaffected by the sulfhydryl modifying reagents. It is stable in EDTA buffer.  Reconstitution Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile PBS containing 0.1% endotoxin-free recombinant human serum albumin. Stability & Storage Use a manual defrost freezer and avoid repeated freeze-thaw cycles. In general: 12 months from date of receipt, -20 to -80°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -80°C under sterile conditions after reconstitution. How to make Stock Solution  Proteinase K Stock Solution - 20 mg/ml (Download PDF format) Instructions Tris-CaCl2 buffer PH8.0 (200mM Tris PH8.0+3mM CaCl2)Measure 5 ml of 200mM Tris Buffer (pH 8.0), RNase free. Add 1.66 mg (3mM) calcium chloride (CaCl2) to the Tris Buffer and dissolve.  5ml Stock Solution (20mg/ml)Measure 2.5 ml of the Tris-CaCl2 Buffer (pH 8.0) into a centrifuge tube. Add 100 mg Proteinase K (YPK-K-100GM). Mix gently to dissolve the Proteinase K.  Sterilize the solution with a 0.22 m filter.  Fill to a final volume of 5 ml with 100% glycerol (add 2.5ml glycerol).  Mix until completely dissolved.                   Store in aliquots at -20°C for 1 year.           3. Suggested Work Concentration: 0.05~1mg/ml Note: Proteinase K interacts with nucleases. To ensure maximum Proteinase K activity, use water that has been treated with 0.1% DEPC
