Fibrinogen and fibrin related chains in reduced human plasma as well as the bonds interlinking partially cross-linked fibrin from plasma clots have been studied by means of 1D- and 2D electrophoresis and Western blotting. Immunovisualization of reduced plasma or partially cross-linked fibrin with monoclonal antibodies specific for the alpha-chains or the gamma-chains have shown that several bands represent material belonging to both chains. In order to decide whether these bands constitute alpha gamma-chain hybrids or superimposed alpha- and gamma-chain dimers, the cross-linked material was separated according to both isoelectric point (pI) and molecular weight (MW) using Pharmacia's Multiphor II system. Western blotting of the second dimension gels revealed that partially cross-linked fibrin contains alpha s gamma t-chain hybrids and gamma-polymers, in addition to the well-known gamma-dimers and alpha-polymers. The main alpha s gamma t-chain hybrid has a pI between that of the alpha- and the gamma-chains, a MW of about 200 kDa and contains A alpha-chains with intact fibrinopeptide A (FPA). It was also observed that soluble fibrinogen/fibrin complexes as well as partially cross-linked fibrin contain degraded alpha-dimers with MWs close to the gamma-dimers. These findings demonstrate that factor XIII-catalyzed cross-linking of fibrin is a more complex phenomenon than earlier recognized.
