General description

Alternative to DFP and PMSF. An irreversible inhibitor of trypsin-like serine proteases. Inhibits trypsin and thrombin in equimolar concentration. Acts on C1r, C1s, Factor Xa, and plasmin, requiring a 5- to 10-fold excess for complete irreversible inhibition. Inhibitory activity is approximately 1000-fold greater than that of PMSF.
An alternative to DFP and PMSF. Specific irreversible inhibitor of trypsin-like serine proteases. Inhibits trypsin and thrombin in equimolar concentrations. Acts on C1r, C1s, Factor Xa and plasmin, requiring a 5- to 10-fold excess for complete irreversible inhibition. Inhibitory activity is approximately 1000-fold greater than that of PMSF. Stability is pH dependent: t½ = 20 min at pH 6.0; 6 min at pH 7.0; 1 millisecond at pH 8.0.
