Fura-2 is a widely used UV-excitable
fluorescent calcium indicator. Upon calcium binding, the
fluorescent excitation maximum of the indicator undergoes a
blue shift from 363 nm (Ca2+-free) to 335 nm (Ca2+-saturated),
while the fluorescence emission maximum is relatively
unchanged at ~510 nm. The indicator is typically excited at
340 nm and 380 nm respectively and the ratio of the
fluorescent intensities corresponding to the two excitations
is used in calculating the intracellular concentrations.
Measurement of calcium concentration using this ratioing
method avoids interference due to uneven dye distribution
and photobleaching (Bright, G.R., et al, in Fluorescence
Microscopy of Living Cells in Culture, Part B, (Methods in
Cell Biology, Vol. 30), Academic Press (1989) p. 157).
Fura-2 has been used in many cellular systems and
applications, particularly in microscopic imaging.
