High Molecular Weight Kininogen (HK) is a nonenzymatic cofactor of the contact activation system. HK is thought to have two functions in the contact activation system. First, HK links prekallikrein to a negatively charged surface thereby allowing activation to kallikrein by surface bound Factor α-Xlla. HK also forms a complex with Factor XI and accelerates its activation to XIa by α-Xlla. Also HK serves as a source of Bradykinin, a potent Vasoactive peptide important in hypotension studies. The protein purity is determined by SDS-PAGE
