Protonex™ Red 780 AM Cell-Permeable

Protonex™ Red 780 AM is the cell-permeable version of Protonex™ Red 780. Protonex™ Red 780 dye works by changing its fluorescence intensity depending on the pH of the environment. Protonex™ Red 780 is minimally fluorescent at a basic pH and maximally fluorescent at an acidic pH. When Protonex™ Red 780 is bound to an acidic intracellular target, it becomes highly fluorescent and emits near-infrared light when excited by a red laser. By measuring the fluorescence intensity of Protonex™ Red 780, one can label or monitor the acidic intracellular targets in live cells.
