Physicochemical properties of the diabetogenic factor and its complex with heparin

: The diabetogenic factor (DGF) isolated from the human blood and the blood of rats with diabetes mellitus was shown to be a protein homogeneous at electrophoresis in gel of polyacrylamide, with the molecular weight of 60,000 D. The interaction of DGF with heparin results in the formation of a complex in which the factor's properties are blocked and those of heparin as a anticoagulant are preserved.
