| 摘 要： | 为了合成恩诺沙星（enrofloxacin，EFLX）完全抗原，制备兔源多克隆抗体血清,试验通过活化酯法将小分子的EFLX偶联到牛血清白蛋白（BSA）和鸡卵清白蛋白(OVA)上，形成偶联物EFLX-BSA和EFLX-OVA，以EFLX-BSA为免疫原免疫兔，以EFLX-OVA为检测原通过ELISA方法检测兔血清效价。结果表明，免疫兔血清效价都在1∶51200以上，其中2号兔效价最高，达到1∶204800，敏感性好，半数抑制浓度IC50为169.91 ng/mL，检测范围为37.52～302.31 ng/mL。本试验成功制备了EFLX完全抗原，获得了敏感的兔源多克隆抗体血清，为以后ELISA试剂盒和胶体金试纸条的研发奠定了基础。

| Abstract: | The purpose of this paper was to synthesize complete antigen of enrofloxacin （EFLX），and to prepare the rabbit polyclonalantibody.Ovalbumin （OVA） and bovine serum albumin （BSA） were used as protein carriers to synthesize small molecule drugs EFLX complete antigens by active ester method.The conjugates formed in this way was EFLX-BSA and EFLX-OVA，the serum titer was detected by use of EFLX-BSA immunogen and EFLX-OVA coating antigen by ELISA.The results showed that the serum titer detection result of three rabbits were all above 1∶51200，the second were the highest of all，its result was 1∶204800 and the sensitive was good.The result of indirect competitive ELISA indicated that this method had a linear detection range from 37.52 to 302.31 ng/mL （R2＝0.9838），with IC50 values of 169.91 ng/mL.In this paper，the immunogen and coating antigen were successfully synthesized，and prepared the good sensetive of rabbit poloclonal antibody from the serum. This experiment obtained high antibody titer，which could lay the foundation for the development of the ELISA kit and colloidal gold test strip. |
