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.

Using the calcium sensitive probe Fura 2, we determined the 340/380 nm wave-length ratios by measuring alterations in calcium homeostasis in isolated myotubes from cultured skeletal muscle specimens.
We conclude that measuring calcium homeostasis with Fura 2 was useful to test the effects of propofol.
