[The N-terminal peptide of the hexon of human adenovirus type 2: its chemical synthesis and antigenic properties].

Peptides corresponding to the N-terminal section of protein of a hexone of the 2nd type human adenovirus have been synthesized. Being conjugated with a carrier of BSA they induced formation of antibodies which reacted both with peptides and with viral proteins. Sera to native proteins were also bound to synthetic peptides. Immunogenicity strengthening in peptides conjugated with synthetic polyelectrolytes is shown. The N-terminal section of hexon is supposed to participate in formation of an antigenic determinant possessing group specificity.
