Purification and Properties of Human Coagulation Factor
Blood coagulation Factor M was purified 100,000fold from fresh frozen human plasma to apparent homogeneity with a yield of 30% based on coagulation assay. The molecular weight estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was 48,000. Factor VI1 is composed of a single polypeptide chain with the NHz-terminal sequence Ala-Asn-AlaPhe-Leu-(G1a)-(Gla)-Leu-(Arg)-Pro. It is co...
متن کاملPurification and Characterization of Human Coagulation Factor
We have purified human coagulation Factor V 6,000fold to homogeneity from citrated plasma using polyethylene glycol 6000 precipitation, adsorption of Factor V to barium citrate, DEAE-Sepharose chromatography, and gel filtration on Ultrogel AcA 34 (yield 21%). Human Factor V is a single polypeptide chain before and after disulfide bond reduction with an apparent M, = 335,000 as determined by ele...
متن کاملTissue factor-dependent autoactivation of human blood coagulation factor VII.
We recently showed that single-chain zymogen factor VII is converted to two-chain factor VIIa in an autocatalytic manner following complex formation with either cell-surface or solution-phase relipidated tissue factor apoprotein (Nakagaki, T., Foster, D. C., Berkner, K. L., and Kisiel, W. (1991) Biochemistry 30, 10819-10824). We have now performed a detailed kinetic analysis of the autoactivati...
متن کاملAcquired deficiency of coagulation factor VII
Factor VII (FVII) is found in small amounts in plasma and has a very short half-life in circulation. FVII is vitamin K-dependently synthesized in the liver. As such, hepatopathies, vitamin K deficiency, or use of vitamin K antagonists is the cause of acquired deficiency. Other types of acquired FVII deficiencies are rare.1 Here we describe a case of acquired factor VII deficiency associated to ...
متن کاملAffinity purification of human tissue factor: interaction of factor VII and tissue factor in detergent micelles.
Tissue factor, a known initiator of blood coagulation, was found to be active in Triton X-100. A system consisting of tissue factor, factor VIIa, calcium ions, and coagulation factor X generated activated factor X at an appreciable rate. Based on this observation, we coupled human and bovine factor VII to a solid support. Each column bound tissue factor, solubilized in Triton X-100, in a specie...
