摘要: 本试验通过碳二亚胺法,将半抗原氧氟沙星与载体牛血清白蛋白(BSA)和卵清白蛋白(OVA)偶联,制备得到氧氟沙星免疫原和包被原,并制备抗氧氟沙星的单克隆抗体,初步研制测定氧氟沙星的ELISA试剂盒,经过测试,对鱼肉样本中氧氟沙星的检测限为1 μg/kg,添加回收率在62.8%~97.7%之间,批内、批间试验的相对标准偏差均小于10%。

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
