Clone Host Grade Applications
Polyclonal Goat Serum E
Human plasma contains at least two distinct forms of kininogen, the carrier molecule of bradykinin, which can be distinguished by their physical, chemical and immunochemical properties. They are designated high-molecular-weight kininogen (HMWK) and low-molecular weight kininogen (LMWK). HMWK (MW 110000) and LMWK (MW 50000) both liberate bradykinin following the action of kallikrein. HMWK circulates as a non-enzymatic factor that is central to contact activation reactions. LMWK plays no known role in the activation of coagulation. Normal adult plasma levels are 7mg/100ml for HMWK as determined by electroimmunodiffusion and 9mg/100ml based on haemagglutination inhibition assays and RIA. Low plasma kininogen levels are seen in newborn and pre-term infants. HMWK is absent in congenital kininogen deficiency of the named affected families Fitzgerald and Reid; Williams and Flaujeac lack both HMWK and LMWK. The condition is associated with the decreased fibrinolytic activity and kinin formation but is asymptomatic.
