    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.
