Activation of Prekallikrein with Factor a-XIIa produces the enzymatically active Kallikrein. Kallikrein is a serine protease which consists of a heavy chain (molecular weight 52,000) and light chains (molecular weights either 36,000 or 33,000) linked by disulphide bridges. Kallikrein possesses enzymatic activity towards Factor XII, High Molecular Weight Kininogen, Plasminogen, Factor XI, Factor IX, Factor VII, prorenin and the complement system. After activation, the activating enzyme Factor XIIa is removed by affinity chromatography. Human Kallikrein purity is determined by SDS-PAGE and shows complete reduction upon incubation with 2-mercaptoethanol.
