The activation and function of surface-bound Hageman factor in human plasma are dependent upon both high molecular weight (HMW) kininogen and prekallikrein. HMW kininogen does not affect the binding of Hageman factor to surfaces, but it enhances the function of surface-bound Hageman factor as assessed by its ability to activate prekallikrein and Factor XI.(More)
The localization of kallikrein in human exocrine organs was studied with a direct immunofluorescence method. In the submandibular and parotid salivary glands, kallikrein was found apically in the striated duct cells whereas it was absent from the main excretory ducts or present only as a weak luminal rim. Kallikrein was not found in the acinar cells or in(More)
An RIA for human HMW kininogen, capable of detecting 150 pg of antigen, has been developed. Antibody to HMW kininogen was purified by immunoaffinity chromatography, and double-antibody precipitation was used to separate free and bound antigen. Of the LMW kininogens only one of the forms tested (B3.2) showed significant cross-reaction (2%). Bradykinin and(More)
Patients lacking high molecular weight (HMW) kininogen have profound abnormalities of the Hageman factor-dependent pathways of coagulation, kinin formation, and fibrinolysis. The ability of HMW kininogen to potentiate the Hageman factor fragments (HFf) activation of prekallikrein and Factor XI in plasma was studied. HFf only partially converted Factor XI to(More)
The normal metabolic turnover of plasma kininogens was studied by measuring the disappearance of intravenously administered radiolabeled human and monkey plasma kininogens from the circulation of healthy adult rhesus monkeys. Curves obtained by plotting log radioactivity against time could be expressed as double exponential equations, with the first term(More)
