A two-step procedure for the purificaton of hepatitis B surface antigen (HBsAg).
Hepatitis B surface antigen (HBsAg) was purified by a simple, rapid, two-step procedure comprising chromatography on dextran sulfate-Sepharose 4B, followed by preparative rate zonal centrifugation on a sucrose gradient. A 230-fold purification of HBsAg was achieved with a yield of about 80%.
