Abstract
Yeast cells are genetically engineered to synthesize and assemble hepatitis B surface antigen particles containing 55 additional amino acids encoded by the hepatitis B virus preS gene. These particles are composed of a 28,000 dalton protein and efficiently bind polymerized human albumin. Antibodies to the polyalbumin receptor epitope of this particle may interfere with the postulated polyalbumin-mediated binding of HBV to hepatocytes and may therefore be particularly efficient in preventing the disease.
