Subunit structure of fragment D from fibrinogen and cross-linked fibrin.
The different species of Fragment D were purified from plasmin digests of either fibrinogen or highly cross-linked fibrin and examined electrophoretically in sodium dodecyl sulfate on polyacrylamide gels before and after reduction by ,&mercaptoethanol. It was found that Fragment D from cross-linked fibrin is approximately twice the size of that from fibrinogen, which indicates that the COOH-ter...
متن کاملCharacterization of fragment E from fibrinogen and cross-linked fibrin.
Fragment E, a terminal plasmin digestion product of fibrinogen or fibrin, contains portions of the alpha, beta, and gamma chains linked by disulfide bonds. In this study, Fragment E from fibrinogen and fully cross-linked fibrin were purified by gel filtration of the soluble fraction from heated plasmin digests of either fibrinogen or fibrin or by step-wise chromatography of terminal plasmin dig...
متن کاملSubunit structure of human fibrinogen, soluble fibrin, and cross-linked insoluble fibrin.
The three unique polypeptide chains of human fibrinogen differ significantly in molecular weight. Cross-linkage of fibrin by fibrin-stabilizing factor results in the rapid formation of cross-links between gamma-chains and a slower formation of cross-links between alpha-chains. beta-Chains are not involved directly in the cross-linking of fibrin. Reduced, cross-linked fibrin contains uncross-lin...
متن کاملPrimary structure of human fibrinogen and fibrin. Isolation and partial characterization of chains of fragment D.
Fragment D has been isolated as an apparently single molecular weight species (molecular weight about 100,000) from plasmin digests of humman fibrinogen, using a combination of affinity chromatography on insolubilized "fibrin monomer" and gel filtration. This fragment consists of three chains with molecular weights of 15,000 (Dbeta), 42,500 (Dgamma1) or 39,500 (Dgamma2), and 14,000 (Dalpha) hel...
متن کاملSeverity of peripheral atherosclerosis is associated with fibrinogen and degradation of cross-linked fibrin.
Immunohistochemical studies of human atherosclerotic lesions have demonstrated the occurrence of fibrin deposition and its degradation in the arterial wall. We studied fibrinogen, the generation of thrombin, and the degradation of fibrin in 40 patients with stable peripheral arterial occlusive disease of varying severity, as assessed by the ankle/brachial pressure index and duplex ultrasonograp...
