Function and Immunochemistry of Prekallikrein-High Molecular Weight Kininogen Complex in Plasma

RESUMO

Plasma from individuals with high molecular weight (HMW) kininogen deficiency has been reported to be deficient in prekallikrein as measured by radial immunodiffusion, prekallikrein coagulant activity, and/or kaolin-activated arginine esterase activity. The discovery that prekallikrein and HMW kininogen circulate as a complex in plasma led us to reevaluate the antigenic and functional properties of prekallikrein in HMW kininogen-deficient plasma as well as in normal plasma.
