5 mg/mL MTT solution
General Information
| Product Introduction | MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide) is widely used for determination of cell proliferation and cytotoxicity. The MTT can be reduced by succinate dehydrogenase in mitochondria of living cells to form crystalline dark purple product formazan. Formazan was deposited in cells, but dead cells do not. The formazan can be solubilized in dimethyl sulfoxide (DMSO).The absorbance (OD value) was measured at the wavelength of 490 nm or 570 nm. The number or activity of living cells could be determined by the OD value. Within a certain range of cell numbers, the amount of MTT crystal formation was proportional to the number or activity of living cells. |
