Fura-2 pentapotassium is a cell-impermeable scaled fluorescent dye designed for intracellular calcium imaging. It has an emission wavelength of 510 nm and excitation wavelengths of 340 nm or 380 nm. The ratio of its fluorescence intensity at 340 nm to 380 nm is proportional to the intracellular Ca2+ level.
