针对鸡蛋中泰妙菌素的残留问题,通过半抗原及抗原设计合成、动物免疫及细胞融合筛选,成功得到可特异、灵敏识别泰妙菌素的单克隆抗体,并建立了泰妙菌素的化学发光酶免疫分析方法(CLEIA)。采用棋盘法结合单因素实验优化策略,确定最佳反应条件为:包被原质量浓度0.26 µg/mL,抗体质量浓度0.94 µg/mL,反应体系为0.02 mol/L的PBS(pH 7.4)缓冲液,酶标二抗质量浓度及其稀释液和反应时间分别为2 μg/mL、PBST和40 min。在该条件下,建立了泰妙菌素的CLEIA方法,其IC,50,为0.54 ng/mL,检出限(LOD,IC,10,)为0.03 ng/mL,线性检测范围(IC,20,~IC,80,)为0.17~1.74 ng/mL,且与其它功能结构类似物无明显交叉反应,特异性良好。将建立的CLEIA方法用于鸡蛋实际样品的检测,加标回收率为100%~118%,相对标准偏差(RSD)小于10%,结果与HPLC-MS/MS(,r,2, = 0.998 7)一致,表明该方法适用于鸡蛋样品中泰妙菌素残留的快速筛查。
A chemiluminescence enzyme immunoassay(CLEIA) method was established for the monitoring of tiamulin residues in egg samples,based on a monoclonal antibody with excellent specificity and sensitivity obtained by synthesizing antigen to immunize BALB/c mice and cell experiments.The optimal conditions were finalized as follows:the coating antigen concentration:0.26 μg/mL,the antibody concentration:0.94 µg/mL,the reaction buffer system:PBS(0.02 mol/L,pH 7.4),and the dilution buffer,the concentration and the reaction time for the enzyme-labeled secondary antibody were PBST buffer,2 µg/mL and 40 min,respectively.Under the optimal conditions,a CLEIA method for tiamulin detection was established,with an IC,50, of 0.54 ng/mL,a limit of detection(LOD,IC,10,) of 0.03 ng/mL,and a linear detection range (IC,20,-IC,80,) of 0.17-1.74 ng/mL.There was no obvious cross-reaction between the method and the other structural and functional analogs of tiamulin.The CLEIA method was used for the detection of real egg samples.The spiked recoveries ranged from 100% to 118%,with the relative standard deviations(RSDs) less than 10%. The test results of the developed CLEIA had a good correlation with those of HPLC-MS/MS(,r,2, = 0.998 7),indicating that the method was suitable for the detection of tiamulin residues in egg samples.
