| Description | Tartrazine (Acid Yellow 23) is a food additive that belongs to a class of artificial dyes and contains an azo group; it has significant genotoxic effect , may be harmful to health and its prolonged use could trigger carcinogenesis. |
| In vitro | We assessed the cytotoxicity of Tartrazine by 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide test and the response of DNA repair through comet assay (alkaline version). We used different concentrations of the dye, ranging from 0.25-64.0 mM. The results demonstrated that Tartrazine has no cytotoxic effects. However, this dye had a significant genotoxic effect at all concentrations tested. Although most of the damage was amenable to repair, some damage remained higher than positive control after 24 h of repair[2] |
