Application

MTT Formazan has been used in cell viability assay.[1][2][3]

Biochem/physiol Actions

MTT assay is a colorimetric reaction, generally used to examine cell viability. It involves the enzymatic reduction of a yellow-colored, water-soluble, 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) to purple-colored, water-insoluble, MTT-formazan. This reaction is catalyzed by mitochondrial dehydrogenase and only occurs in viable cells. Thus, the amount of blue formazan is proportional to the number of viable cells. The absorbance of the formazan solution is analyzed spectrophotometrically at 570 nm.

    Will Not Work For MTT Proliferation Assay

    I accidentally bought this thinking it was MTT salt to use in a cell proliferation assay but it is MTT Formazan, the water insoluble end product! Therefore, it is useless for the assay. I suppose you could use it as a control to optimize your buffer for solubilizing the insoluble Formazan. The description for this product is misleading and should clarify that this is not what you need for an MTT assay, and refer the customer to MTT salt. That said, this is a nice purple crystalline powder and insoluble in water consistent with MTT Formazan, if that is what you actually want.
