Here we report the development of a novel, homogeneous, single-addition reagent that allows researchers to measure the relative number of live and dead cells in culture wells. This assay technology gives ratiometric, inversely proportional values of viability and cytotoxicity that are useful for normalizing data to cell number. Lastly, this reagent is fully compatible with additional fluorescent and luminescent chemistries.
