Human Kininogen (Single Chain High Molecular Weight)
Cat No.
CZY-028
Description
High Molecular Weight Kininogen (HK) is a non-enzymatic 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 of Kallikrein by surface bound Factor a-XIIa. HK also forms a complex with Factor XI and accelerates its activation to XIa by a-XIIa. Additionally HK serves as a source of Bradykinin, a potent vasoactive peptide important in hypotension studies. The protein purity is determined by SDS-PAGE.
