  • Purification of hepatitis B surface antigen
    Patent number: 3994870
    Abstract: After a polyethylene glycol purification procedure, virus particles, viral components and virus associated particles having concanavalin A binding sites are further purified by subjecting such particles or components to affinity chromatography utilizing insoluble concanavalin A as a chromatography adsorbent and an eluant capable of interacting with concanavalin A to thereby inhibit the binding of the virus particles or components to the insoluble concanavalin A. Specifically, the insoluble concanavalin A may be concanavalin A linked to agarose beads and the eluant may be methyl-.alpha.-D-mannopyranoside. Specifically, these procedures may be utilized to purify hepatitis B antigen (HB Ag) particles.
