Complex formation of crosslinked fibrin oligomers with agarose-coupled fibrinogen and fibrin. 1977

R von Hugo, and R Hafter, and A Stemberger, and H Graeff

Soluble oligomers of fibrin were produced by limited incubation of fibrinogen with thrombin in the presence of calcium2 positive earth, cysteine and factor XIII. They were separated from fibrinogen by gel filtration. Gamma-gamma dimers were demonstrated in fractions from the void volume and the shoulder prior to the fibrinogen peak. These fractions were subjected to affinity chromatography on agarose-coupled fibrinogen and fibrin. Cross-linked oligomers of fibrin were adsorbed to agarose-coupled fibrin, whereas no adsorption occured during affinity chromatography on agarose-coupled fibrinogen. This indicates that crosslinked fibrin oligomers have no affinity to fibrinogen, yet readily form complexes with fibrin.

UI MeSH Term Description Entries
D009842 Oligopeptides Peptides composed of between two and twelve amino acids. Oligopeptide
D002846 Chromatography, Affinity A chromatographic technique that utilizes the ability of biological molecules, often ANTIBODIES, to bind to certain ligands specifically and reversibly. It is used in protein biochemistry. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) Chromatography, Bioaffinity,Immunochromatography,Affinity Chromatography,Bioaffinity Chromatography
D005337 Fibrin A protein derived from FIBRINOGEN in the presence of THROMBIN, which forms part of the blood clot. Antithrombin I
D005340 Fibrinogen Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
