摘要:

为了产生同时检测恩诺沙星和环丙沙星的抗体,本研究采用戊二醛法制备突出恩诺沙星和环丙沙星共同结构的人工抗原。免疫Balb/c 小鼠的结果显示:使用糖基化载体所制备的免疫抗原,能够大幅提高所产生特异性抗体的滴度。通过细胞融合,筛选出一株对恩诺沙星和环丙沙星IC50 值分别为9.6ng/mL 和10.2ng/mL 的单克隆抗体。

Abstract:

In order to generate a monoclonal antibody with specificity to simultaneously detect enrofloxacin and ciprofloxacin, glutaraldehyde was used to prepare the artificial antigens with common structures of enrofloxacin and ciprofloxacin exposed as the major epitopes. Balb/c mice were immunized with the prepared immunogens. Results indicated that glycosylated BSA used for immunogen synthesis resulted in a higher antiserum titer when compared to unglycosylated BSA. A monoclonal antibody with respective IC50 values of 9.6 ng/mL and 10.2 ng/mL to enrofloxacin and ciprofloxacin was successfully prepared through cell fusion.

Key words: enrofloxacin, ciprofloxacin, glycosylated carrier, veterinary drug residues, artificial antigen, immunological effect
