Synthetic peptide antigens of tetanus toxin.
In this study the immunochemical structure of the heavy chain polypeptide from tetanus toxin was studied. Numerous antigenic determinants were identified by probing a set of overlapping peptides derived from the amino acid sequence of tetanus toxin with polyclonal anti-toxoid antibody preparations. Synthetic antigens representing continuous epitopes were prepared and used to immunize mice. The capacity of the resulting anti-peptide antibodies to react with tetanus toxin in vitro and in vivo was determined. The majority of antibodies bound to tetanus toxin and three epitopes capable of eliciting neutralizing antibodies were identified.
