Product Description: Fura-2 pentapotassium is a scaled fluorescent dye that can be used for intracellular calcium imaging with the Kd value of 140 nM. Fura-2 pentapotassium has an emission wavelength of 510 nm and excitation wavelengths of 340 nm or 380 nm and the ratio of 340/380 fluorescence intensity is proportional to the intracellular Ca2+ level[1][2].
Formula: C29H22K5N3O14
