Monoclonal antibodies against adenovirus type 5: preparation and preliminary characterization.

Eight different hybridoma cells lines producing monoclonal antibodies against the major antigens of human adenovirus type 5 have been obtained. They were selected by screening initial hybridomas by the fluorescent antibody technique followed by radioimmune precipitation and they reacted with hexon, penton, fibre and 100K polypeptides. Five apparently different epitopes against the hexon antigen were detected showing a spectrum of activity against the hexons of other serotypes, suggesting that the hexon contained a variety of subgroup specificities as well as the previously described group and type specificities.
