The analysis of cell viability, cytotoxicity, cell cycle state, cell proliferation, and cell death are critical to most cell-based studies.
Understand your options, and choose the right assay to fit your experimental needs.

Cell viability assays that measure the rates of cellular metabolism/enzyme activity
Including MTT, MTS, resazurin and similar assays, mitochondrial membrane potential-dependent dyes, esterase cleaved dyes, ATP and ADP assays, and assays that measure glycolytic flux and oxygen consumption.
Cytotoxicity assays that test for cytolysis/membrane leakage
Including LDH enzyme leakage assays, and membrane impermeable dyes like 7-AAD.
Cell proliferation and cell cycle assays
Including assays using dye dilution, BrdU/EdU and DNA staining dyes. These are used to monitor the growth of a cell population, detect generations of daughter cells, or analyze the cell cycle state of a cell population. You can use also these tests to assay cell viability.
Apoptosis/cell death analysis
Such as Annexin V, TUNEL, and caspase assays.
Remember: no one method gives a perfect view of cell viability, proliferation, or cell death. It is almost always most effective to combine several different methods.
