Cellular assay kits allow researchers to investigate many aspects of cell health, including viability, proliferation, cytotoxicity, metabolism, apoptosis, and more. Such assays generally measure specific cellular properties such as the presence of metabolites, changes in cellular components, membrane integrity, and enzyme activity. This diverse product catalog contains assay kits from trusted suppliers; many including ready-to-use reagent sets to enable straightforward and optimized cell-based assays. Filters are provided to help simplify the product search. Flow cytometry is a common cell analysis application, as well as immunofluorescence and microscopy. Choose between fluorescence, colorimetric, or luminescent detection methods depending on the nature of the experiment. Visit the supplier page for more information, such as assay methods, protocols, included reagents, and more.
XXT assays use the tetrazolium salt XXT (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) to measure the metabolic activity of cells. It is a colorimetric assay that reduces a yellow tetrazolium salt to an orange formazan dye in the presence of metabolically active cells. The amount of dye formed correlates with the number of viable cells in the sample. XXT assays can be used to study cell proliferation in response to growth factors, nutrients, and stimuli for the assessment of growth inhibitors and to measure cytotoxicity.
