ABSTRACT:
An improved method for purification of HBs antigen comprising passing a partially purified HBs antigen prepared from blood plasma or serum through a column filled with an anion exchanger which may be equilibrated with a buffer solution having a specific ionic strength and pH level, and further passing the resulting effluent through a column filled with a cation exchanger which may be equilibrated with a buffer solution having a specific ionic strength and pH level. The HBs antigen obtained by the present invention is highly purified and is useful for preparing vaccine for preventing Viral Hepatitis Type B.
