The amount of such a soluble fibrin proved to be a linear function of the D fragment concentration. Three fibrin monomer preparations obtained in different ways were used. All of them showed similar properties as to the modifications with D fragment. The solubilzing activity of D fragment in the equilibrium system could sharply be raised by increasing ionic strength or pH.
