fura-2
fu·ra-2 (fū'ră), A fluorescent indicator that binds calcium; it is excited at longer wavelengths when free of calcium than when calcium is bound; the ratio of fluorescence intensity at two excitation wavelengths provides a measure of free calcium ion concentration; may be injected into cells to monitor moment-to-moment changes in intracellular free calcium ion concentration.
