Mononuclear cells in blood are used in vitro for vaccine immunization assay. We describe an optimized peripheral blood mononuclear cells culture infection with Salmonella typhimurium for plasmid DNA vaccine carrier. A eukaryotic expression green fluorescent protein coding sequence plasmid was introduced to an attenuated strain of Salmonella typhimurium. Peripheral blood mononuclear cells were infected with log phase bacteria (MOI). After one hour incubation with bacteria, 100 IU/ml penicillin, 100mg/ml streptomycin and 50mg/ml gentamycin were added to each plate. By 24 hours incubation delivery of plasmid was confirmed by fluorescent microscope.
