APMSF is an irreversible inhibitor of plasma serine proteases (trypsin-like proteases), which are specific for the basic amino acid side chains lysine and arginine. If applied in equimolar ratios of enzyme and inhibitor, immediate, complete inhibition of trypsin and thrombin occurs. At a 5 to 10fold excess of inhibitor, factor Xa (bovine) and plasmin (human) will be inhibited. Acetylcholine esterase is insensitive.
APMSF is a more potent inhibitor than PMSF. Its effective concentration is 10 - 50 μM or 2.5 μg/ml, respectively (e. g. ref. 2). Stock solutions are prepared in water at concentrations of 1 - 5 mM. It is stable, when stored aliquoted at -20°C.
