A process for obtaining a material possessing glucose tolerance factor activity and capable of binding with insulin including the steps of (i) contacting a eukaryotic cell mass with a mixture of water and alcohol to form a water phase and an alcohol phase; (ii) separating the alcohol phase from the water phase and isolating a water phase extract; and (iii) subjecting the water phase extract to gel exclusion chromatography, eluting all material having a molecular weight of approximately 720 to 1120 to obtain a material possessing glucose tolerance factor activity and capable of binding with insulin.
