Epitope Mapping of 3A Protein Using Monoclonal Antibodies.

(SVA), an emerging pathogen causing vesicular disease in pigs, poses a significant threat to the swine industry. The nonstructural protein 3A of SVA plays an essential role in the viral replication cycle. In this study, we immunized mice with the prepared SVA 3A protein and produced two monoclonal antibodies (mAbs), AG4 and 2F3.
