PBFI, AM is a cell-permeant, fluorescent ion indicator that is relatively selective for potassium ions in the presence of other mono-valent cations. PBFI’s spectral response to ion-binding permits a ratiometric calculation of ion concentration that cancels artifacts of photobleaching, dye concentration gradients, and dye leakage. PBFI AM has been used to investigate intracellular potassium concentrations and gradients in a variety of living tissues. The excitation wavelength of PBFI varies with potassium ion concentration and shifts to shorter wavelengths with increasing potassium concentration. The ratio of fluorescence intensity at 500 nm when excited at 340/380 nm, as well as the fluorescence emission ratio at 410/590 nm with excitation at 340 nm have both been used for ratiometric calculation of ion concentration. .
