A capillary zone electrophoresis-based method to evaluate the cytotoxicity of substances to Caco-2 cells was established. The estimation of the injected cell number (500-5000) and the minor effect of injection condition on cytotoxicity determination were investigated. Caco-2 cells the best model of the intestinal absorptive epithelium, were treated with substances and then stained with Trypan Blue and fixed with paraformaldehyde. The treated Caco-2 cells were detected simultaneously at 590 nm and 214 nm, and the absorbance ratio of the two wavelengths (R(590/214) ) can reflect simultaneously the loss of cell membrane integrity and the degradation/leak of intracellular components and indicate the cytotoxicity of substances. The cytotoxicity of the four substances sodium sulfite (Na(2) SO(3) ), methyl mercury (MeHg), paclitaxel (PTX), and cadmium chloride (CdCl(2) ) were determined and compared. There was no obvious cytotoxicity caused by 20 μM Na(2) SO(3) for 24 h treatment, and the toxicity of the other three toxicants was sequenced as: CdCl(2) > MeHg> PTX. The results are in good agreement with the references and the conventional Trypan Blue exclusion counting assay.
