Fura-2 pentapotassium（Cat No.:R001089）is a fluorescent calcium indicator used to measure intracellular calcium ion (Ca²⁺) concentrations. It is a highly sensitive compound that exhibits changes in fluorescence when it binds to calcium, enabling real-time monitoring of Ca²⁺ dynamics in living cells. Fura-2 pentapotassium is commonly used in cell biology and pharmacology research to study calcium signaling, cell activation, and various physiological processes. The pentapotassium form improves its solubility in aqueous solutions, making it suitable for fluorescence-based imaging techniques, including fluorescence microscopy and fluorescence spectroscopy in live cell assays.
