Technology Description: The invention uses hybridoma cell lines and monoclonal antibodies to detect theantibiotic, ceftiofur, in meat and milk. Ceftiofur is a broad spectrum cephalosporin exhibitsexcellent antimicrobial activity and is used in the treatment of respitory diseases in animals. Themonoclonal antibodies may be incorporated into kits for detection and quantification of ceftiofur.The invention replaces expensive and sophisticated equipment currently used to test trace levels ofceftiofur in milk or meat. The invention also requires less labor that current tests, allowingproducers to better manage the use of ceftiofur.
