Enterovirus 71 (EV71) is a leading cause of severe hand, foot, and mouth disease (HFMD) and neurological complications in children. The VP1 capsid protein is the most immunogenic structural protein of EV71, essential for viral entry, receptor binding, and strain classification. VP1 contains highly conserved neutralizing epitopes, making it an ideal target for EV71 diagnostics, vaccine development, and therapeutic antibody studies. Catalina’s stringently validated EV71 VP1 antibodies provide precise and reproducible detection of VP1 expression. These antibodies are indispensable tools for research into EV71 pathogenesis, immunogenicity, neutralization mechanisms, and HFMD intervention strategies.
