A comparison of bovine prothrombin, factor IX (Christmas factor), and factor X (Stuart factor).
A comparison has been made of the electrophoretic behavior, chemical composition, amino-terminal sequence, and immunological properties of bovine prothrombin, factor IX (Christmas factor), and factor X (Stuart factor). Some immunological crossreactivity was found between the antibody to prothrombin and factor X although prothrombin and factor X differ substantially in amino-acid and carbohydrat...
متن کاملChristmas factor (IX) defect in a case of haemorrhagic thrombocythaemia.
The mechanism of bleeding in haemorrhagic thrombocythaemia is obscure. Although by definition there is always a raised platelet count, the haemorrhagic episodes cannot be satisfactorily correlated with the level of the count. In fact, thrombocythaemia can exist without bleeding manifestations (Fanger, Cella, and Litchman, 1954). The most commonly occurring laboratory defect is an abnormal bleed...
متن کاملImmunoaffinity purification of factor IX (Christmas factor) by using conformation-specific antibodies directed against the factor IX-metal complex.
Factor IX is a vitamin K-dependent blood clotting zymogen that is functionally defective or absent in patients with hemophilia B. A method of immunoaffinity chromatography has been developed for a one-step high yield purification of factor IX directly from plasma. The technique utilizes conformation-specific antibodies that bind solely to the metal-stabilized factor IX conformer, but not to the...
متن کاملTissue factor-dependent activation of tritium-labeled factor IX and factor X in human plasma.
Recent investigations have suggested that the activation of factor IX by factor VII/tissue factor may be an important alternative route to the generation of factor Xa. Accordingly, we have compared the tissue factor-dependent activation of tritium-labeled factor IX and factor X in a human plasma system and have studied the role of proteases known to stimulate factor VII activity. Plasma was def...
