MTT (Thiazolyl Blue Tetrazolium Bromide) is a yellow compound used in laboratory assays to measure cell viability and metabolic activity. The 1g size is ideal for small-scale experiments or screening assays, where MTT is used to assess cellular metabolism by measuring the conversion of the tetrazolium salt into a colored formazan product. The reaction is commonly used in cytotoxicity tests, cell proliferation assays, and mitochondrial activity studies. MTT assays are widely applied in cell biology, pharmacology, and toxicology research to evaluate the effects of drugs, chemicals, and environmental factors on living cells. This reagent provides a simple and reliable method for assessing cell health.
