    摘要: An improved process for the preparation of hepatitis B antigen by subjecting biological fluid containing heptatitis B surface antigen to isopycanic banding wherein the step gradient is NaBr. Faster and more economical processing is obtained by multiple loading of the step gradient, either NaBr or conventional gradients.

    摘要: An improved process for the preparation of hepatitis B antigen by subjecting plasma of hepatitis B donors to isopycanic banding wherein the step gradient is NaBr. Faster and more economical processing is obtained by multiple loading of the step gradient, either NaBr or conventional gradients.

    摘要: 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.
