General description

Native, single chain, high molecular weight Kininogen from human plasma. Non-enzymatic cofactor of the contact activation system. Links prekallikrein to negatively charged surfaces, thereby allowing activation to kallikrein by surface-bound Factor a-XIIa. Also circulates in plasma in complex with Factor XI, that may play a role in the activation of Factor XI to Factor XIa by Factor α-XIIa. Serves as a source of bradykinin, a potent vasoactive peptide important in hypotension studies.
