Abstract:The Short Time Exposure (STE) test evaluates eye irritation potential using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. MTT assays may underpredict results for some substances that directly reduce MTT (i.e., MTT reducers) or interfere with absorbance because of their strong color (i.e., strongly colored substances). Based on previous research, we selected 25 substances as MTT reducers. Of these, 13 were expected to be MTT reducers at 5% dilution (5% MTT reducers) of the STE test… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
