Abstract
High purity HB.sub.s Ag is injected into guinea pigs to stimulate formulation of HB.sub.s Ab-positive serum. Gamma globulins containing HB.sub.s Ab are separated from the serum and the globulin fraction containing HB.sub.s Ab is isolated and coupled to a Sepharose gel. HB.sub.s Ag from HB.sub.s Ag-positive plasma is adsorbed on the gel by formation of an HB.sub.s Ab-HB.sub.s Ag complex. HB.sub.s Ag is eluted from the column and dialysed.
