Abstract: Hexapeptide Lys-Gly-Pro-Asp-Ser-Gly analogous to the immunodominant fragment 141146 of the epitop A of the influenza virus A(H3N2) hemagglutinin is synthesized. Conjugated with thyreoglobulin and hemocyanine, the hexapeptide induced formation of highly specific antibodies with heterolitic properties in CBA mice. Antihexapeptide antibodies interact not only with the homologous antigene but also with hemagglutinin and influenza virus. Choice of the hexapeptide sequence is discussed.
