Rhod-2

Rhod-2 is a fluorescent calcium chelator bearing a rhodamine-like fluorophore. Similar to Fluo-3, Rhod-2 has excitation and emission spectra that do not undergo significant shift with changing calcium concentrartion. The indicator is essentially nonfluorescent before Ca²⁺ binding but becomes more fluorescent with increasing Ca²⁺ concentration. The longer excitations and emissions of Rhod-2 (~556/576nm) make the indicator useful for experiments in cells and tissues that have high levels of autofluorescence and for experiments where another fluorescent dye of shorter wavelengths is used at the same time. The fluorescent enhancement for Rhod-2 from low [Ca²⁺] to high [Ca²⁺] is smaller than that for Fluo-3, and also Rhod-2 is much less fluorescent than Fluo-3.
