Abstract

The mouse monoclonal and polyclonal antibodies were produced for the detection of intracellular pathogen and potential warfare agent Francisella tularensis. Antibody titers obtained were 1:640 for polyclonal antibodies and 1:320 for monoclonal antibodies. Both antibodies were used in the indirect enzyme-linked immunosorbent assay (ELISA) found to detect F. tularensis whole cells. The limit of detection was 5.4×106 CFU/ml for polyclonal antibodies and 6.9×106 CFU/ml for monoclonal antibodies. The value sample could be distinguished from any concentration of another gram-negative bacterium: Escherichia coli.
