Thiazolyl Blue is a 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. Thiazolyl Blue is used as a direct indicator of cytotoxicity (such as for screening cancer drμgs) and apoptosis. Thiazolyl Blue is also an electron acceptor used for studying NADP-dependent dehydrogenases.常用于基于MTT检测方法的细胞活力、细胞增殖或细胞毒性检测。因为MTT具有正电荷，它可以穿过细胞膜并被线粒体还原形成紫色甲臜染料。溶解MTT甲臜染料需要使用有机溶剂。脱氢酶的检测，染色法。 Thiazolyl Blue is a membrane-permeable yellow dye that is reduced by mitochondrial reductases in living cells to form the dark blue product, MTT Formazan).
