摘要
采用改进的碳二亚胺两步法将强力霉素半抗原与载体蛋白BSA连接制备强力霉素-牛血清白蛋白(BSA-DC)人工免疫抗原,并用同样方法将强力霉素与载体蛋白OVA连接制备人强力霉素-卵清白蛋白(OVA-DC)人工包被抗原。经紫外扫描分析和动物免疫试验证实:强力霉素人工抗原合成成功,强力霉素与BSA的结合比为3∶1,经动物免疫试验所得抗血清效价为2.048×106,完全能够满足强力霉素残留的ELISA检测要求。
In this study,the improved two-step carbodiimide method was used to connecte doxycycline hapten with carrier protein BSA,and doxycycline with the carrier protein OVA to prepare the artificial antigen of doxycycline（BSA-DC） and coating antigen（OVA-DC）,respectively.UV scanning analysis and animal immune tests confirm the success in preparation of artificial antigen,and the combination ratio of doxycycline and BSA is 3∶1 by calculating.At the same time,the results showed that high titers of 2.048×106 anti-DC serum were produced by BSA-DC immunized rabbit.It provided a necessary condition for ELISA detecting doxycycline residues.
