Rhod-2, with fluorescence excitation maxima at 552 nm and emission maxima at 581 nm, was first introduced in 1989.  Rhod-2 is essentially non-fluorescent before Ca2+ binding, becoming more fluorescent with increasing Ca2+ concentration. The longer excitations and emissions of Rhod-2  make the indicator useful for experiments in cells and tissues that have high levels of autofluorescence...Read More
