摘要:

针对目前食品安全领域中氯霉素的检测,建立一种快速灵敏的氯霉素毛细管电泳免疫分析方法。该方法对氯霉素检测的线性范围和最低检测限分别为0.008~5μg/L 和 0.0016μg/L。与相应固相酶联免疫分析ELISA相比,对氯霉素的检测灵敏提高了约20 倍且有效缩短了分析时间。建立的氯霉素毛细管电泳免疫分析方法对动物源性食物(牛奶、鸡肉和鱼肉)进行分析,得到氯霉素在实际样品中的检测限为0.035μg/kg。

Abstract:

A rapid and sensitive approach to performing competitive immunoassay for chloramphenicol in animal-derived food using capillary electrophoresis (CE) with laser-induced fluorescence (LIF) detection was presented. The assay exhibited a linear range of 0.008-5μg/L and a limit of detection of 0.0016μg/L. The sensitivity of this assay was almost 20 times higher than that of the solid-phase ELISA assay and the time consumption was shortened. In the real sample analysis, a detectable level of 0.035μg/kg was obtained.

Key words: chloramphenicol, competitive immunoassay based capillary electrophoresis with a laser-induced fluorescence detector (CEIA-LIF), solid-phase ELISA assay, rapidity, sensitivity, limit of detection
