应用胶体金免疫层析法对动物组织中的氯霉素残留进行检测,研究该方法的灵敏度、假阳性率、假阴性率及特异性。结果表明,用胶体金免疫层析法测定猪肉、鸡肉、鱼、虾中的氯霉素,检测限均为0.31ag/kg,假阳性率和假阴性率皆为0%;方法的特异性较好,对其他抗生素无交叉反应;检测加标样本的结果与液相色谱.串联质谱法基本一致。可见,该方法简便、快速、准确、稳定,可作为动物组织中氯霉素残留现场快速检测的一种有效手段。
應用膠體金免疫層析法對動物組織中的氯黴素殘留進行檢測,研究該方法的靈敏度、假暘性率、假陰性率及特異性。結果錶明,用膠體金免疫層析法測定豬肉、鷄肉、魚、蝦中的氯黴素,檢測限均為0.31ag/kg,假暘性率和假陰性率皆為0%;方法的特異性較好,對其他抗生素無交扠反應;檢測加標樣本的結果與液相色譜.串聯質譜法基本一緻。可見,該方法簡便、快速、準確、穩定,可作為動物組織中氯黴素殘留現場快速檢測的一種有效手段。

A gold immunochromatographic assay (GICA) was used to detect the residues of chloramphenicol in animal tis- sues. The sensitivity, false positive rate (FPR), false negative rate (FNR) and specificity of the method were studied. The re- suits showed that the detect limit of GICA was 0.3pg/kg. FPR and FNR were both 0%. The specificity was good and there was no cross-reactivity with any other antibiotics. The results of GICA and liquid chromatographic tandem mass spectro- metry (LC-MS/MS) were in accordance. The method is simple, rapid, accurate and stable, and suitable for the on-site rapid detection of chloramphenicol residues in animal tissues.
