摘  要：
对检测水产品中呋喃唑酮代谢物(AOZ)和氯霉素(CAP)药物残留的两种方法——化学发光免疫分析(CLEIA)和酶联免疫分析(ELISA)法进行了比较研究。结果表明:两种药物残留检测中,CLEIA分析方法的线性范围和检出限均优于ELISA法,且两种免疫分析法的添加回收率均具有很好的相关性;用CLEIA法检测AOZ的检出限为0.01μg/kg,线性范围为0.01~2.56μg/kg,检测CAP的检出限为0.016μg/kg,线性范围为0.025~6.400μg/kg;用ELISA法检测AOZ的检出限为0.1μg/kg,线性范围为0.10~1.62μg/kg,检测CAP的检出限为0.05μg/kg,线性范围为0.05~4.05μg/kg;用CLEIA法检测CAP的批内变异系数(RSD)为5.5%~11.3%,批间RSD为12.3%~20.9%,检测AOZ的批内RSD为6.6%~11.1%,批间RSD为15.6%~18.3%。研究表明,用CLEIA法检测水产品药物残留较ELISA法检出限低、线性范围宽,虽然检出CAP和AOZ的变异系数均高于ELISA法,但仍符合《兽药残留酶联免疫试剂(盒)备案参考评判标准》的规定。

摘  要：
Detection of furazolidone metabolite( AOZ) and chloramphenicol( CAP) residues in fish and fishery products was comparatively studied by chemiluminescence enzyme-linked immunoassay( CLEIA) and traditional colorimetric enzyme-linked immunosorbent assay( ELISA). The results showed that CLEIA had better linear range and detection limit than ELISA,and a close correlation of recovery rate was shown in the two methods. In CLISA,the detection limit was about 0. 01 μg /kg for AOZ,and about 0. 016 μg /kg for CAP and the linear range was from 0. 01 to 2. 56 μg /kg for AOZ,and from 0. 025 μg /kg to 6. 400 μg /kg for CAP. In ELISA,however,the detection limit was 0. 1 μg /kg for AOZ and about 0. 05 μg /kg for CAP and the linear range was from 0. 1 to 1. 62μg/kg for AOZ and from 0. 05 to 4. 05 μg/kg for CAP. The satisfactory precisions of the assay were found in CLEIA,with variation coefficient of 5. 5%-11. 3% in the intra-assay and 12. 3%-20. 9% in the inter-assay for CAP,and with variation coefficient of 6. 6-11. 1% in the intra-assay and 15. 6%-18. 3% in the inter-assay for AOZ,within the record reference evaluation standard of ELISA residues of veterinary drugs(kit).
