Influence of the double-headed bis(Gly-Pro-Arg-Pro-amido)peg ligand on the degree of covalent polymerization of fibrinogen with factor XIIIa. This experiment was carried out according to the procedure described in the legend to Fig. 3. However, the reaction products (ca. 40 μg per tube) were analyzed, without reduction, by electrophoresis in agarose (2%)/0.1% SDS, as given in Materials and Methods.
