Abstract: Ofloxacin was coupled with BSA as an immunogen and with OVA as a coating antigen using the coupling agent EDC. Monoclonal antibodies against ofloxacin and its enzyme linked immunosorbent assay kit were prepared and established,respectively. The limit of detection was 1 μg/kg in fish, and the recovery range was 62.8% to 97.7%. The intra and inter assay RSD were both less than 10%.

Key words: ofloxacin; monoclonal antibodies; enzyme linked immunosorbent assay kit; rapid detection
