The effect of different factor XIII inhibitors (competetive inhibition, interference with active center SH-groups in different ways, Ca2+ depletion) on the sequence of the γ-dimerization and α-polymerization of fibrin is examined by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAE) (reduced material). They all inhibit either γ-dimerization and a-polymerization or a-polymerization alone irrespective of the factor XIII inhibitory mechanism.

Non-crosslinked fibrin and fibrin clots of different degrees of crosslinking are digested with plasmin and the lysate tested in SDS-PAE (non-reduced material) and crossed agarose gel Immunoelectrophoresis (CAIE). The digests contain Fragment D and Fragment D-D respectively and Fragment E. An additional Fragment E with less anodic mobility in CAIE, and not demonstrable in SDS-PAE, is seen in increasing amounts with increasing γ-dimerization, α-polymerization does not further change the CAIE patterns.
