Cyto-X is a ready-for-use cell viability reagent for proliferation and cytotoxicity assays. When added to cell culture, a highly water-soluble tetrazolium salt is reduced by dehydrogenases in live cells to form an orange colored formazan product that is soluble in culture medium. The amount of formazan product is directly proportional to the enzymatic activity of dehydrogenases and the number of living cells. With its high sensitivity and low cytotoxicity, Cyto-X outperforms traditional assays using other tetrazolium salts such as MTT, XTT, MTS or WST-1.


(Click to Enlarge) Cyto-X colorimetric cell counting reagent is more sensitive and user friendly, requiring fewer steps with less wait time.  The formulation also greatly reduces cytotoxicity compared to other products.
