Abstract
A process for producing an intravenously-administrable gamma globulin solution substantially free of contaminating viruses by fractionating an impure gamma globulin solution and then treating the purified gamma globulin, with a solvent-detergent for viral inactivation and a heat treating for viral inactivation. Thereafter, denatured impurities, residual solvent and aggregate generated by the heat treatment are removed from the gamma globulin.
