Synthesis and release of Hageman factor (Factor XII) by the isolated perfused rat liver.

Synthesis and release of Hageman factor (Factor XII) by the isolated perfused rat liver.

The site of synthesis of Hageman factor (HF, Factor XII) has not been previously demonstrated with certainty. We have studied the production and release of HF in the isolated perfused rat liver and have compared rates of synthesis in this system with absolute rates of degradation measured in vivo. Rat livers, perfused for 5 h with a recycling fluid consisting of a perfluorochemical emulsion (Fl...

The activation of plasminogen by Hageman factor (Factor XII) and Hageman factor fragments.

Activation of plasminogen through surface-mediated reactions is well recognized. In the presence of kaolin, purified Hageman factor (Factor XII) changed plasminogen to plasmin, as assayed upon a synthetic amide substrate and by fibrinolysis. Kinetic studies suggested an enzymatic action of Hageman factor upon its substrate, plasminogen. Hageman factor fragments, at a protein concentration equiv...

Studies on the inhibition of ellagic acid-activated Hageman factor (factor XII) and Hageman factor fragments.

Hageman factor (HF, factor XII) that has been exposed to Sephadex-ellagic acid gels is a single-chain species (HFea) with amidolytic properties for the synthetic substrate H-D-phenylalanyl-L-pipecolyl-L-arginine p-nitroanilide. Earlier we reported that amidolysis was suppressed by incubation of HFea with specific antiserum. The present study provides additional evidence that the amidolytic prop...
