Recombinant Hepatitis surface antigen preparation is a recombinant surface antigen, AY subtype of the Hepatitis B virus. It is produced using a Saccharomyces cerevisiae. expression system.

Four major serotypes of the hepatitis B virus are adentified according to variability of the surface antigen, defined by a common 'a' determinant and mutually exclusive determinant pairs 'd/y' and 'w/r'. Hence, the subtypes are adw,adr, ayw and ayr. Further subdivision of these major subtypes has identified additional minor subtypes of the virus (Magnius & Norder 1995).
