Abstract

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.
