Description

General description

A reversible inhibitor of trypsin that binds to trypsin in a stoichiometric, pH-dependent manner (K_d = 500 nM at pH 7.8).

Reversible inhibitor of trypsin that binds to trypsin in a stoichiometric, reversible and pH-dependent manner (K_d = 0.5 nM at pH 7.8). Also inhibits, to a lesser degree, chymotrypsin, kallikrein, plasmin, and other serine proteases.

Biochem/physiol Actions

Kd = 500 nM at pH 7.8 against trypsin

Primary Target
trypsin

Warning

Toxicity: Standard Handling (A)
