A tetrazolium dye commonly used for colorimetric measurement of cellular metabolic activity and viability.
Macklin Thiazolyl Blue Tetrazolium Bromide, commonly known as MTT, is a tetrazolium compound used in colorimetric cell-viability and proliferation assays.
Metabolically active cells reduce the yellow MTT reagent to insoluble purple formazan. After the crystals are dissolved using a suitable solvent, the resulting absorbance can be measured with a microplate reader. Assay conditions should be optimized for the selected cell type and experimental system.
