title: The composed antigenic structure of the adenovirus hexon protein.
abstract: Three panels of MAbs were prepared against AV1, AV35, and BAV2 hexons, respectively. It was shown, that in all cases, antibodies are developed against the genus specific determinant of the adenovirus hexon. The other MAbs specified numerous identical or overlapping epitopes on the hexon types studied. The epitopes could be characterized as intertype-, intersubgenus-, subgenus- and type-specific ones beside the genus-specific determinant based on the RPs of the MAbs from indirect ELISA and passive HA results. The identical epitopes are present in more than one copy on the trimeric form of the hexon capsomer. The epitopes on the hexon molecule could be separated into three antigenic sites, of which one antigenic site is characterized by seven epitope clusters (antigenic site II). Monoclonal antibodies were able to precipitate different hexon types in gel diffusion tests by which the differentiation of the distinct epitopes seemed to be possible. With the help of monoclonal antibodies to AV1 hexon, 17 hours after the infection, hexons (or epitopes) were detected in the cytoplasm and in the nucleus of the infected cells showing different distribution patterns in indirect immunofluorescence assay.
