Identification of viral antigenic determinants by monoclonal antibodies directed against Chilo iridescent virus (iridovirus type 6). Brief report.

Monoclonal antibodies (McAbs) obtained against Iridovirus type 6 (CIV) were characterized by Western blotting and/or immunoprecipitation. Seven McAbs were found to be strongly reactive with viral polypeptides of molecular weights 16 K and 18 K by Western blotting. Two McAbs were directed against a complex composed of 30 K, 50 K, and 100 K polypeptides, but failed to react with either of these free polypeptides. This finding could explain the faint reactivity of these McAbs in Western blotting and immunoprecipitation. The reactivity of the other McAbs with their antigenic determinants is also discussed.
