MTT 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium Bromide, Thiazole Blue Membrane-permeable yellow dye that is reduced by mitochondrial reductases in living cells to form the dark blue product, MTT-formazan. Spectrophotometric measurement of MTT-formazan at 540 or 570 nm allows quantitation of cell viability. Used as a direct indicator of cytotoxicity (such as for screening cancer drugs) and apoptosis. An electron acceptor used for studying NADP-dependent dehydrogenases. 产品信息 Form Yellow solid Molar mass 414.3 Purity ≥98% by argentometry Contaminants Sulfated ash: ≤0.5%; heavy metals: ≤0.001% Solubility PBS Chemical formula C18H16BrN5S RTECS XF8060000 CAS number 298-93-1 商店和运输信息 Storage +15°C to +30°C Ship Ambient Temperature Only Harmful & Carcinogenic / Teratogenic
