How to determine cell viability
WebJan 3, 2024 · A viable cell count allows one to identify the number of actively growing/dividing cells in a sample. The plate count method or spread plate relies on bacteria growing a colony on a nutrient medium. The colony becomes visible to the naked eye and the number of colonies on a plate can be counted.

Cell viability assays use a variety of markers as indicators of metabolically active (living) cells. Examples of markers commonly used include measuring ATP levels, measuring the ability to reduce a substrate, and detecting enzymatic/protease activities unique to living cells. See more When using our plate-based assays, choosing the right type of plate is dependent on your research needs. If microscopic observation of cells is desired, opaque clear-bottom plates are required. In general, … See more Multiplexing more than one assay is a versatile approach that can provide more information from a single sample. For example, you can … See more Usually there is a trade-off between the cost of the reagent and the quality of the assay or the convenience it provides to the user.
