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.
WST-1 assay kits are designed to evaluate cell proliferation and viability through the use of water-soluble tetrazolium (WST) salts. The light red WST-1 (4-[3-(4-Iodophenyl)-2-(4-nitro-phenyl)-2H-5-tetrazolio]-1,3-benzene sulfonate) is converted to a dark red formazan by mitochondrial reductase enzymes and the electron acceptor 1-methoxy phenazine methosulfate. WST-1 assay kits can be used to measure cell response to growth stimulators and inhibitors, and to analyze the cytotoxicity of pharmaceutical compounds. WST-1 is advantageous as the reaction can occur outside cells, does not require a solubilization step, and is less toxic to cells. Visit the supplier page for more product information.
