Observation and measurement of cell viability and proliferation is a crucial aspect of many cell-based applications, including cellular imaging, cell culture, functional screening, and drug discovery. Because cellular biology is inherently complex and can be investigated via various parameters, there are similarly many types of cell-based tests and assays. These include assays for live/dead cells, cytotoxicity, apoptosis, mitochondrial membrane potential, reactive oxygen species. Activity of key enzymes involved in cell health can also be tested, such as caspases and dehydrogenases. Use the filters on the left to help narrow down the search for the right cell viability assay.
Apoptosis is a form of programed cell death that is vital for all multicellular organisms to ensure proper development. However, perhaps there is an excessive or an insufficient amount of apoptotic activity. This could be an interesting finding and a researcher may want to understanding the reasoning behind this by using an apoptosis assay kit. The various applications of apoptosis assays include flow cytometry, immunoassays, immunocytochemistry, staining, and western blots.
