Cell Health: Viability, Proliferation, Cytotoxicity, and Cellular Function

What is cell viability?

Cell viability refers to the number of healthy cells in a population and can be evaluated using assays that measure enzyme activity, cell membrane integrity, ATP production, and other indicators. These methods can employ luminescent, fluorescent, or colorimetric readouts as indicators of general cell viability or even specific cellular pathways. Cytotoxicity and cell viability assays are often used to assess a drug or other treatment’s effect, and are valuable tools in the search for new therapeutics, as well as advancing our understanding of how normal cells function.

Cell viability, cell proliferation, cytotoxicity assays

Many assays for cell viability and proliferation, including a variety of cytotoxicity assays, are detected using microplate readers. Viability assays using different detection modes are available, each with their own advantages.
