Rhod-2 is similar to fluo-3 in that
the excitation and emission spectra do not undergo a shift
and the sensor is essentially nonfluorescent before Ca2+
binding but becomes more fluorescent with increasing Ca2+
concentration. The absorption (556 nm) and emission (576 nm)
maxima of rhod-2, however, are longer than those of fluo-3.
The longer absorption and emission wavelengths of rhod-2 may
make it useful for some applications where autofluorescence
is a problem, or 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+] was smaller than that for fluo-3, and also
in general rhod-2 is somewhat less fluorescent than fluo-3.
