Corn Trypsin Inhibitor

Corn Trypsin Inhibitor (CTI) is a specific and potent inhibitor of human factor XIIa. It is purified from sweet corn by solvent extraction and chromatographic methods. A suggested inhibitory concentration is 24 fold molar excess over the enzyme concentration. CTI purity is determined by SDS-PAGE and shows no reduction upon incubation with 2-mercaptoethanol.
