Abstract
Gamma globulin concentrates are stabilized against anticomplement activity generation during lyophilization by inclusion in the concentrate of a physiologically acceptable, substantially nonsurface-active hydrophilic macromolecule. The improved concentrates may be safely administered to patients. The main additives to the gamma globulin are a substantially nonsurface-active hydrophilic macromolecule, a protein and a polyol.
