Establishment and Optimization Of Enzyme-Linked Immunosorbent Assay For Zilpaterol Residue Detection
摘要
Abstract
To establish an indirect competitive enzyme-linked immunosorbent assay(ic-ELISA)method for the detection of zilpterol(ZIL)residues,in this study,based on the obtained rabbit anti-ZIL polyclonal an-tibody serum and the prepared complete antigen as the coating source,an ic-ELISA method for the detec-tion of ZIL residues was established by optimizing the reaction conditions;The results showed that the best dilution ratio of rabbit serum was 1:6 000,and the best antigen coating concentration was 2 μg/mL,the half inhibition concentration(IC50)is 0.317 ng/mL,the linear detection range(IC20-IC80)is 0.136-1.181 ng/mL,and the minimum detection limit(LOD,IC10)is 0.081 ng/mL.After optimization,the optimal pH of the detection system is 7.4,the salt concentration is≤0.4 mol/L,the content of methanol,ethanol,ace-tone and DMSO is≤5%,the content of acetonitrile is≤10%,and the concentration of bovine urine in the detection matrix is≤15%.The detection method has good stability and specificity.The addition recovery rate of intra-batch and inter-batch repeated test samples is 101%-1 12%and 101%-120%respectively,and the coefficient of variation is less than 10%,The correlation coefficient between the test results and HPLC-MS test results is R2=0.990 6.The detection method is fast,sensitive,accurate,reproducible and low detec-tion limit,and is suitable for high-throughput detection and on-site rapid screening of ZIL residues.关键词
