MTT Assay Kit ab211091 provides an easy-to-use, non-radioactive, and high-throughput method for measuring cell proliferation, cell viability and cytotoxicity.
The MTT assay protocol is based on the conversion of water soluble MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) compound to an insoluble formazan product.
Viable cells with active metabolism convert MTT into formazan. Dead cells, on the other hand, lose this ability and therefore show no signal. Thus color formation serves as a useful and convenient marker of only the viable cells. The measured absorbance at OD 590 nm is proportional to the number of viable cells.
MTT assay protocol summary:
- replace serum-containing media with serum-free media and MTT reagent in cell cultures
- incubate for 3 hr at 37ºC
- add MTT solvent and incubate for 15 min
- analyze with microplate reader

MTT assay kit ab211091 was used by an Abcam customer (see product review) to assess the cell viability of myeloma cells which have acquired resistance to bortezomib (a proteasome inhibitor used as a cancer therapeutic).
Cells previously treated with 10 nM bortezomib for 1.5 months (RPMI8226-Bortezomib) had significantly improved viability, compared to the parental untreated cell line, when treated for 72 hours with varying concentrations of bortezomib.
HeLa cells were grown in DMEM media supplemented with 10% FBS, harvested using trypsin and counted using Trypan blue and a hemocytometer. Cells were then serially diluted in a clear cell culture plate and incubated for 3 hours with MTT Reagent at 37°C. After incubation, cells were treated with MTT Solvent for 15 minutes at room temperature. Absorbance was measured at OD = 590 nm. Inset graph is an expanded segment of the assay data at lower cell number per well.
