It inhibits proteases such aschymotrypsin, trypsin, thrombin and thiol proteases such as papain. PMSF inhibits serine proteases bysulfonating serine residues at the active site.Storage/Stability:When stored as indicated, PMSF has a shelf-life of three years..Preparation Instructions:PMSF is soluble in anhydrous isopropanol at 35 mg/ml with heating, resulting in a clear to very slightlyhazy, colorless to faint yellow solution.Recommended stock solution: 100 mM in anhydrous isopropanol or anhydrous (100%, not 95%) ethanol.A 200 mM solution in dry solvent is stable for at least 9 months at 2-8° C.PMSF is very unstable in the presence of water. The half-life of aqueous PMSF at 25° C at pH 7.0, 7.5,and 8.0 is 110, 55, and 35 minute respectively.Precautions and Disclaimer:PMSF is considered a highly toxic cholinesterase inhibitor.
