Abstract

The entire hepatitis B Virus pre-S antigen gene linked in one contiguous reading frame to the hepatitis B virus surface antigen gene has been expressed in Saccharomyces cerevisiae. The expressed protein aggregates into a particulate form which displays the major antigenic sites encoded by both domains, thereby highlighting the utility of yeast as a host for the expression of pre-S domains. This protein is useful in in vitro diagnostic systems and as a vaccine for the treatment and prevention of hepatitis B virus-induced diseases and/or infections.
