Factor XI activity and factor XI antigen in homozygous and heterozygous factor XI deficiency.
A relatively potent antiserum against highly purified, unactivated human factor XI antigen was raised in a rabbit. This antiserum, after concentration, neutralized 50% of the factor XI clotting activity of a standard normal plasma at an antiserum dilution of 1/900. The antiserum was used in a neutralization-inhibition assay to study the relation between factor XI clotting activity and factor XI...
متن کاملFactor XI: purification from porcine plasma by affinity chromatography and some properties of factor XI and activated factor XI.
Porcine factor XI and activated factor XI were purified by the introduction of affinity chromatography on high molecular mass kininogen. On the affinity chromatography, it was observed that high affinity exists between porcine factor XI and high molecular mass kininogen. In the preparation, however, factor XII, plasma prekallikrein and high molecular mass kininogen were not detected. The factor...
متن کاملComparison of bleeding tendency, factor XI coagulant activity, and factor XI antigen in 25 factor XI-deficient kindreds.
The relationship of clinical bleeding tendency and factor XI antigen (XI:Ag) in factor XI deficiency was studied in 78 members of 25 factor XI-deficient kindreds. Factor XI:Ag was measured in a competitive radioimmunoassay, using monospecific, heterologous anti-factor XI antibody. 125I-labeled factor XI, and staphylococcal protein A as the precipitating agent. Deficiency of factor XI clotting a...
متن کاملFactor XI deficiency.
That factor XI has a role in normal blood coagulation is evidenced by the fact that patients with deficiency are prone to excessive bleeding after haemostatic challenge. The role of factor XI in physiological processes has become clearer since the discovery that it is activated by thrombin; this fact has contributed to a revised model of blood coagulation. Factor XI deficiency is particularly c...
