[3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide]

Description:
[3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide], commonly known as MTT, is a yellow, water-soluble compound widely used in cell viability assays. Its chemical structure features a tetrazolium ring, which is crucial for its function as a colorimetric reagent. Upon reduction by viable cells, MTT is converted into a purple formazan product, allowing for quantification of cell metabolic activity. MTT is stable under normal conditions but should be stored in a cool, dark place to prevent degradation. It is soluble in aqueous solutions at physiological pH, making it suitable for biological applications. The compound is non-toxic to cells at low concentrations, which is essential for accurate viability assessments. MTT assays are commonly employed in pharmacology and toxicology to evaluate the effects of drugs and other substances on cell health. However, care must be taken when interpreting results, as factors such as cell type and assay conditions can influence outcomes. Overall, MTT is a valuable tool in research for assessing cellular health and proliferation.
