Cell viability assays are widely used in drug discovery for the study of growth factors, cytokines, and cytotoxic agents. High throughput screening, in both early drug discovery compound screening and subsequent drug safety and toxicity studies, require reliable, sensitive, and simple assays with the ability to analyze a large number of samples. Colorimetric cell viability assays using tetrazolium salt, such as MTT, XTT, and WST-1, were developed based on live cell reduction of tetrazolium salt into highly colored formazan compounds (1,2). Similarly, resazurin (blue and nonfluorescent) can be reduced to resorufin (pink and highly fluorescent) in live cells and is therefore used to assess mammalian cell toxicity, viability, migration, and invasion (3-6). Similar to the XTT Cell Viability Kit #9095, the Resazurin Cell Viability Kit does not require radioactive materials, cell fixation, or cell permeabilization, and cells used in this assay may be used for further analysis.
