Alterations in a fluorescent ion indicator's fluorescence intensity or emission wavelength, caused by changes in ion concentration, allow temporal and physical changes to be visualized. These changes can be measured in real time using flow cytometry or fluorescence microscopy and can be used in various research fields including neuroscience, cardiology, and metabolism.
Fluorescent ion indicators provide valuable insights into the effects of drug compounds on cell ion gradients and are compatible with high throughput screening assays. They can be used to identify novel compounds that modulate ion channel activity, understand drug mechanisms of action, and monitor ion dynamics with high sensitivity and selectivity.
