title: alpha1-Antichymotrypsin interaction with cationic proteins from granulocytes.
abstract: Human granulocytes contain cationic proteins with chymotrypsin-like activity. These proteases showed a higher relative affinity for alpha1-antichymotrypsin than for alpha1-antitrypsin but the highest affinity for alpha2-macroglobulin. The complexes between cationic protein and alpha1-antichymotrypsin migrate as beta-globulin on agarose gel electrophoresis.
