Abstract
Methods for producing from human serum, human gamma globulin essentially free of HB.sub.s Ag and products resulting therefrom. Specifically provided are ion exchange resin/buffer systems capable of effectively removing HB.sub.s Ag thought to be closely correlated with viral hepatitis type B infectivity. Additional steps can include ultrafiltration to increase reduction of any virus not removed in the column passage as well as the addition of anti-HB.sub.g to substantially eliminate all infectivity.
