Cell proliferation assays are laboratory techniques used to measure the growth and division of cells. These assays help researchers understand how cells respond to various treatments, such as drugs or environmental changes. By quantifying the number of cells over time, scientists can assess the effects of these treatments on cell health and viability. Common methods for conducting cell proliferation assays include the MTT assay, BrdU incorporation, and cell counting. Each method has its own advantages and can provide insights into different aspects of cell growth. These assays are essential in fields like cancer research and drug development, where understanding cell behavior is crucial.
