FACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY
Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...
متن کاملFactor VIII/von Willebrand factor protein. Galactose a cryptic determinant of von Willebrand factor activity.
The normal Factor VIII/von Willebrand factor protein has the ability to agglutinate or aggregate normal platelets in the presence of ristocetin (von Willebrand factor activity). Removal of greater than 95% of the sialic acid from this protein by neuraminidase did not affect the von Willebrand factor or procoagulant activity. However, oxidation of the penultimate galactose of the asialo Factor V...
متن کاملSubcellular platelet factor VIII antigen and von Willebrand factor
Subcellular membrane and granule fractions derived from human platelets contain factor VIIII antigen and von Willebrand factor activity but not factor VII procoagulant activity. Circulating platelets constitute a significant reservoir of plasma factor VIII antigen, containing approximately 15% of the amount of factor VIII antigen present in platelet-poor plasma. The antibiotic ristocetin, which...
متن کاملKinetics of factor VIII-von Willebrand factor association.
The binding of factor VIII to von Willebrand factor (vWF) is essential for the protection of factor VIII against proteolytic degradation in plasma. We have characterized the binding kinetics of human factor VIII with vWF using a centrifugation binding assay. Purified or plasma vWF was immobilized with a monoclonal antibody (MoAb RU1) covalently linked to Sepharose (Pharmacia LKB Biotechnology, ...
متن کاملThe complex multimeric composition of factor VIII/von Willebrand factor.
We have analyzed the multimeric structure of factor VIII/von Willebrand factor in plasma by sodium dodecyl sulfate electrophoresis using gels of varying porosity and a discontinuous buffer system. Factor VIII/von Willebrand factor bands were identified by reaction with 125I-labeled affinity-purified antibody and subsequent autoradiography. In 1% agarose gels, normal plasma displayed a series of...
