Cell Viability Testing Service

A cell viability assay is often based on assaying ongoing cellular metabolism and enzyme activity, ie measuring factors that reflect the number of living cells in a population. 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.CD BioSciences can provide you with professional cell viability testing service to meet the specific needs of different customers.

Overall solution

• Dye reduction assays

Tetrazolium cell viability assays rely on cellular dehydrogenases to form a colored formazan product, which is measured by absorbance. Other assays use the reduction of resazurin, by electron acceptance from the mitochondrial respiratory chain, to form the fluorescent resorufin.

• ATP and ADP assays

Most assays use a cell membrane permeabilization agent to release ATP; light is produced using ATP-dependent luciferase. Other ATP assays use the ATP-dependent phosphorylation of glycerol (or other substrates).

• Glycolytic flux and oxygen consumption assays

The rate of oxygen consumption indicates the level of cellular metabolic activity. Analysis of intracellular oxygen levels and glycolysis activity allow deeper investigation.
