Product Description: The use of a colorimetric assay for cell growth, proliferation, and survival offers major advantages in speed, cost, and
safety over other assays relying on the use of radioactive compounds (such as 3H-thymidine or 51Cr) (see Cell Injury Assay Kit). Multiwell
scanning spectrophotometers (ELISA readers) can measure large numbers of samples with precision. One of the popular methods developed
toward this end is the MTT assay, which relies on the ability of live but not dead cells to reduce a water-soluble yellow dye, MTT or
3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide, to a water-insoluble purple formazan product (J. Immunol. Methods 65:55, 1983 &
Cancer Res. 47:936,1987). Active mitochondrial dehydrogenases of living cells are believed to cause this conversion. The water insoluble
formazan can be solubilized using DMSO or isopropanol, and the dissolved material is measured spectrophotometrically yielding absorbance as
a function of concentration of converted dye. The assay requires minimal manipulation, is easily automated, and thus is ideally suited to a
program that involves a wide range of cell types and thousands of potential drug agents. Both monolayer and suspension cell cultures can be
assayed using the MTT conversion method. The stability of our specially formulated MTT solution is guaranteed for as least 1 year from the
time of purchase if handled and stored properly. The MTT Solution is sufficient for 5,000 - 10,000 microassays.

& Clinical Application
Mesenchymal stem cells (MSC) were
plated on uncoated (open circle) and
fibronectin-coated (closed circle) dishes.
An MTT cell proliferation assay were
performed to determine the effect of
fibronectin on MSC growth.
