Abstract
Noninstrumental methods of qualitative rapid test for detection of staphylococcal enterotoxin A (SEA) in milk foods sample and brothof using immunochromatography (IC) and dot-assay has been developed. Monoclonal antibodies to SEA with colloidal gold forimmunochromatography; monoclonal antibodies to SEA with colloidal gold or biotinylated monoclonal antibodies and streptavidin-peroxidase conjugate for dot-assay were used to visualize the results. The detection limits, ng/mL: 10 (IC), 20 (dot-assay with antibody-colloidal gold), 10 (dot-assay with STR-HRP), 4 (ELISA). Time of assay, min: 25 (IC), 60 (dot-assay with antibody-colloidal gold), 70 (dot-assay with STR-HRPO, 150 (ELISA).
