title: Concentration and purification of hepatitis B antigen with polyethylene glycol and polyelectrolyte 60, a cross-linked copolymer of isobutylene maleic anhydride.
abstract: A simple two-step procedure is described for the concentration and purification of hepatitis B antigen. The antigen is precipitated by polyethylene glycol and then adsorbed on and eluted from an insoluble polyelectrolyte, polyelectrolyte 60, which is a cross-linked copolymer of isobutylene maleic anhydride.
