WebUnder certain conditions, such as alkaline pH values, PMSF may have a half-life of only 35 minutes. High-salt conditions (3 M), often used to precipitate proteins, may also reverse the inhibition of PMSF. Pefabloc SC is recommended as a non-toxic, water-soluble, and water-stable alternative. Storage conditions (working solution): 15 to 25 °C WebGeneral Description PMSF is an irreversible inhibitor of serine and cysteine proteases, such as trypsin, chymotrypsin, thrombin and papain and mammalian acetylcholinesterase. It is recommended to dissolve PMSF in DMSO or Ethanol as it degrades in water.
