MTT Reagent A by Molecular Depot is an MTT reagent, the yellow tetrazolium that living cells reduce to a dark blue formazan. Cellular reductases convert the tetrazolium into an insoluble formazan, so the colour formed reflects metabolic activity. It is used in cell viability, proliferation and cytotoxicity assays read by absorbance after the formazan is dissolved. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
