Abstract：
:Purified hepatitis B surface antigen (HBsAg) of subtype ay was solubilized in guanidinium chloride and submitted to chromatography on Sepharose 4B in the presence of guanidinium chloride. The polypeptides P1 (Mr = 24,000) and P2 (Mr = 29,000) were eluted in the same fraction with a minor contaminant (Mr = 40,000). Large amounts of these two polypeptides were obtained in a single step. This technique which constitutes a method for large-scale purification of the P1 and P2 polypeptides should permit more complete characterization of the P1 and P2 polypeptides and of their antigenic determinants.
