Abstract

Particles of hepatitis B virus surface antigens (HBsAg) are produced by expression from a culture of CHO cells transfected with a plasmid, recovering the culture supernatant which, after sterilising filtration, is concentrated and subjected to a fractional precipitation with PEG, the precipitate being taken up and subjected to a zonal velocity centrifugation and then to a zonal flotation centrifugation, following which chromatography is performed in an anion exchanger medium. The vaccine is noteworthy for its purity and its immunogenicity, in particular for its capacity for inducing anti-pre-S2 antibodies.
