Accurate prediction of the adverse effects of test compounds on living systems, detection of toxic thresholds, and expansion of experimental data sets to include multiple toxicity end-point analysis are required for any robust screening regime. The Alamar Blue assay provides accurate time-course measurements, has high sensitivity and linearity, involves no cell lysis, is ideal for use with post-measurement functional assays, is flexible as it can be used with different cell models, is scalable and can be used with fluorescence- and/or absorbance-based instrumentation platforms, and finally, it is non-toxic, non-radioactive and is safe for the user, and the environment. In vitro bioassays may not be highly predictive of in vivo effects and there may be a need for the development of multiple parameters which would assist in translating in vitro data into meaningful in vivo effects [72]. There is a profusion of data that supports the use of Alamar Blue as a cell viability assay, however, numerous studies have adopted a combinatorial approach to cell viability and cytotoxicity screening and, therefore, utilized different assay chemistries in order to produce the most meaningful and representative in vitro result.
