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.
Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) is a way to detect DNA fragmentation that occurs due to apoptotic signaling cascades. The TUNEL assay relies on nicks being present in the DNA so that terminal deoxynucleotidyl transferase also known as TdT can catalyze the addition of dUTP. This dUTP could be labeled with a hapten or fluorophore so that detection is possible. If you’re looking to detect the later stages of apoptosis, a TUNEL assay kit would be ideal for you.
