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.
A comet assay, also known as a single cell gel electrophoresis assay, is a detection method to detect DNA damage in a eukaryotic cell. The cells are embedded in agarose on a microscope slide and then lysed to form nucleoids of supercoiled DNA. The gel electrophoresis of the lysed cell results in structures that resemble comets that can be seen via fluorescence microscopy. The intensity of the comet tail in comparison the head is a reflection of how many breaks there are in the DNA.
