Mag-fura-2, AM is a cell membrane-permeant, short-wavelength fluorescent ion indicator for intracellular magnesium ion measurements. Mag-fura-2’s spectral response to ion-binding permits a ratiometric calculation of ion concentration that cancels artifacts of photobleaching, dye concentration gradients, cell thickness and dye leakage. Live cells are passively loaded with Mag-Fura-2, AM by incubation with the cell-membrane permeant AM esters. Once internalized, cytosolic esterases cleave the AM esters to liberate the active tetra-carboxylate ligand. The excitation wavelength of Mag-fura-2 varies with Mg2+ concentration and shifts to shorter wavelengths with increasing Mg2+ concentration. The ratio of fluorescence intensity at 510 nm when excited at 340/380 nm is used for ratiometric calculation of ion concentration. Mag-fura-2 has also been used as a low affinity fluorescent indicator for intracellular Ca2+ measurements where high concentration Ca2+ transients would saturate higher affinity indicators. .
