One of the most commonly used methods for assessing cell viability is the MTT assay, which measures the ability of living cells to reduce the yellow MTT dye to purple formazan crystals.

The MTT assay determines the effect of a compound on cell viability ... following which cell viability is assessed by measuring absorbance via a plate reader. A reduction in absorbance, compared to ...

The HA was then used in a lymphocyte assay using cells from a normal volunteer. Toxicity was assessed by using MTT (tetrazolium) as a marker in an automated microtitre plate assay. Over a range of ...
