Antibody response to two synthetic peptides corresponding to residues 45-68 and 69-79 of the major protein of hepatitis B surface antigen.
Peptides corresponding to amino acid residues 48-65 and 69-79 of the major polypeptide component of hepatitis B surface antigen (HBsAg) were synthesized and conjugated to protein (bovine serum albumin and keyhole limpet hemocyanin) and fully synthetic (polyglutaraldehyde and cross-linked liposomes) carriers. The peptide-liposome conjugates appeared the most consistent in eliciting antibodies to HBsAg. Results of competition assays between each of the free synthetic peptides and HBsAg for antibodies suggested that the synthetic analogues and the corresponding segments on intact HBsAg are structurally closely related.
