Cell Meter™ Live Cell ATP Assay Kit
Adenosine triphosphate (ATP) plays a fundamental role in cellular energetics, metabolic regulation and cellular signaling. It is referred as the "molecular unit of currency" of intracellular energy transfer to drive many biological processes and chemical synthesis in living cells. ATP also serves as a signaling molecule for cell communication and plays an important role in DNA and RNA synthesis. It is localized in mitochondria, where cellular respiration occurs. ATP levels can be used to measure cell proliferation and cell cycle dynamics. AAT Bioquest offers a variety of bioluminescence, fluorescence and colorimetric assay kits to determine ATP level in solutions. Cell Meter™ Live Cell ATP Assay Kit enables researchers to monitor ATP levels in live cells using ATP Red™, a cell-permeable red fluorescent imaging probe for detecting ATP. ATP Red™ is designed to monitor ATP concentrations in the mitochondria of living cells. The probe has minimal cross reactivity to AMP, ADP, CMP, CDP, CTP, UMP, UDP, UTP, GMP, GDP or GTP.
The fluorescence images of HeLa cells co-stained with ATP Red™ and MitoLite™ Green FM in a 96-well black-wall clear-bottom plate. HeLa cells were stained with ATP Red™ for 15 min and then incubated with 100 nM MitoLite™ Green FM (Cat#22695) for another 30 minutes. Washed twice with assay buffer before imaging. ATP Red™ and MitoLite ATP Red™ signals overlay well. (Far right image) The cells were imaged using a fluorescence microscope with a Cy3/TRITC and FITC filters.
