Abstract:Protective immunity against shigellosis is thought to be determined by the O-antigen side chains of the lipopolysaccharide (LPS) molecule. To study possible common protective epitopes, monoclonal antibodies reacting with Shigella flexneri 2a LPS were generated from BALB/c mice infected ocularly with the virulent serotype 2a strain S. flexneri 2457T and tested against a panel of S. flexneri LPSs by enzyme-linked immunosorbent and immunoblot assays. Four monoclonal antibodies were identified, all of which showed… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
