IAEDANS is an organic fluorescent dye that is used in molecular biology often for labeling proteins, since it is readily reacts with thiol groups of the amino acid cysteine ​​and in the neutral pH - range water-soluble. Since the fluorescence strong solution and is dependent on the environment, he is quite good for binding measurements by changing the polarization of the emitted radiation, or by FRET. The dye is excited by ultraviolet radiation at a wavelength of 336 nm and emits in the region around 490 nm, the absorption at 336 nm is carried out with an extinction coefficient of the 5700th
