Preparation and characterization of monoclonal antibodies to foot-and-mouth disease virus type Asia-1.

Eight clones of hybrid cells secreting monoclonal antibodies to foot-and-mouth disease virus type Asia-1 were prepared; three of them neutralized viral infection. The specificity of THE monoclonal antibodies was analyzed by various immunoenzyme assays using 146S viral particles, trypsin-treated 146S particles, 12S particles, and certain viral polypeptides. The epitopes unique for virus type Asia-1 and conservative among several types were detected on the surface of viral particles. Epitopes on the surface of viral particle were mapped.
