Abstract

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
