Adenosine 5'-triphosphate Magnesium Salt is widely used in biochemical research and molecular biology as an energy source in enzymatic reactions. It plays a critical role in studies involving ATP-dependent enzymes, such as kinases, ATPases, and synthetases, where it provides the necessary energy for phosphorylation and other metabolic processes. In cellular assays, it is employed to mimic physiological conditions, enabling the investigation of cellular energy metabolism and signaling pathways. Additionally, it is utilized in the preparation of cell culture media to support cell growth and maintain cellular functions. Its application extends to diagnostic kits for measuring ATP levels, which are indicators of cell viability and metabolic activity. In drug discovery, it is used to screen compounds that modulate ATP-dependent processes, aiding in the development of therapeutic agents.
