MTT

MTT is slightly soluble in methanol, but has very low solubility in ethanol. It barely dissolves in ether, acetone, or ethyl acetate. MTT is utilized for cell viability detection. Since MTT has a positive charge, it can pass through a cell membrane and is reduced by mitochondria to form a purple color formazan dye. Organic solvent is requried to dissovle MTT formazan dyes.
