We developed a biotin–streptavidin‐based sandwich ELISA for the sensitive and specific detection of Yersinia pestis. In this assay, the F1 capsular protein and Y. pestis were captured by anti‐F1 mouse monoclonal antibody followed by detection with biotinylated‐anti‐F1 rabbit polyclonal antibody and HRP‐conjugated streptavidin. The developed F1 ELISA could detect not only the F1 protein up to 29 and 17 pg/ml but also Y. pestis up to 177.8 and 129.2 CFU/ml in PBS buffer and human serum, respectively. In addition, the F1 ELISA did not show any cross‐reactivity with various proteins and bacterial strains.
