[Studies on polypeptides. IX. Synthesis and antigen specificity of pre-S region fragments of hepatitis B surface antigen].
Seven peptide fragments of HBsAg Pre-S region have been synthesized by liquid phase and solid phase methods. All peptide fragments were linked to protein carrier by carbodiimide and glutaraldehyde methods. The antigen specificity of the peptide--protein conjugates was assayed by anti-HBsAg polyclonal antibodies and anti--"a" monoclonal antibody. P1 and P5 were found to have higher antigen specificity.
