Treatment with papain of human 7 S gamma globulin which has specific hemagglutinating antibody activity results in 3.5 S univalent fragments contaminated by intact bivalent globulin. The technique described in this report permits separation of univalent antibody fragments from the contaminating undigested molecule.
