MTT (Thiazolyl blue tetrazolium bromide) CAS:298-93-1

MTT, or Thiazolyl blue tetrazolium bromide, is a commonly used reagent in cell biology and biochemistry to assess cell viability and proliferation. When MTT is added to living cells, it is reduced by mitochondrial enzymes to form a purple formazan product. This conversion is often used as an indicator of metabolic activity within the cells. The MTT assay is widely employed in drug discovery, cytotoxicity testing, and the study of cell signaling pathways. Its application allows researchers to measure the effects of various compounds on cell health and function, making it a valuable tool in understanding cellular behavior and responses to treatments.
