Properties of sulfatides in factor-XII-dependent contact activation.
Incubation of normal human plasma with low amounts of sulfatides resulted in the initiation of intrinsic coagulation and the appearance of kallikrein activity. The optimal initiation of procoagulant and kallikrein amidolytic activity was dependent on the presence of factor XII, high molecular weight kininogen, and prekallikrein. Since the activated partial thromboplastin clotting times in preka...
متن کاملThe Role of Factor XII in Contact System Activation
Although the excellent review on the contact system by Colman and Schmaier1 that appeared recently in Blood examines the subject in great detail, there are some points that deserve further discussion. A major item in that review is the novel observation, described recently in Blood,2 that prekallikrein (PK) becomes activated when it is bound to high molecular weight kininogen (HK) on endothelia...
متن کاملHuman blood coagulation factor XI. Purification, properties, and mechanism of activation by activated factor XII.
Human blood coagulation Factor XI was purified in 20% yield from plasma by ion exchange chromatography. The specific clotting activity of purified Factor XI was 250 & 20 units/mg implying that its concentration in normal titrated human plasma is 4 pg/ml. The purified Factor XI in its precursor form gave a single protein band on polyacrylamide gels in the presence of sodium dodecyl sulfate with ...
