Enteriditidis. a Analysis of 4 recombinant nanobodies expression by SDS-page. b Determination of 4 recombinant nanobodies by Western blot. c Detection of the 4 recombinant nanobodies specifically binding to the S. Enteriditidis by the indirect ELISA. d Identification the 4 recombinant nanobodies to bind another strain of S. Enteriditidis, three Salmonella strains and five other non-Salmonella strainsBack to article page
