INDO1 pentapotassium（Cat No.:R001088）is a calcium indicator used in fluorescence-based assays to measure intracellular calcium levels. It consists of a fluorescent dye, INDO1, which binds to calcium ions, and is stabilized by five potassium ions in the pentapotassium salt form. Upon binding calcium, the dye undergoes a shift in fluorescence emission, allowing for the detection of calcium fluctuations in cells. INDO1 pentapotassium is commonly used in research involving cellular signaling, neurobiology, and pharmacology to study calcium dynamics, with applications in drug discovery, disease mechanisms, and cell signaling studies.
