Fura -2 is a fluorescent dye (Ca2 ) chelate forms with calcium cations, and is used for the determination of intracellular calcium concentration. Fura -2 is available as Pentapotassium or penta sodium salt.

Properties

Calcium complex may be excited by UV light ( 380 nm to 340 nm) and fluoresces in the visible range. For the photometric determination of the concentration of the emission is observed around 510 nm. The rate of emission at this wavelength is directly proportional to the concentration of ( intracellular ) calcium ions.

Other Fura dyes

In addition to Fura -2 are also still Fura -1 and Fura- 3 is known:
