Soybean Trypsin Inhibitor, ACF

Soybean Trypsin Inhibitor, Animal Component-Free (ACF) is obtained from cultures free of animal-derived materials. This trypsin inhibitor consists of a single polypeptide chain with two disulfide bridges and inactivates trypsin on an equimolar basis. It is able to inhibit chymotrypsin to a lesser extent, but is ineffective against esterolytic, proteolytic, or elastolytic activities of porcine elastase (Vered et al.). Soybean Trypsin Inhibitor has also been shown to inhibit human and bovine thrombin, plasmin, and leukocytic proteases.
