Fura-2 acetomethoxy (AM) is one of the most widely used calcium indicators for homogenous quantitative dual wavelength ratiometric cell measurements. Fura-2 AM is particularly useful for digital imaging microscopy. It is less susceptible to photobleaching than Indo-1. The probe is excited only by UV light, which results in significantly less interference by visible wavelength excitable fluorescent compounds. One application of the probe is as a useful counter screen tool for GPCR and calcium channel hits identified using calcium indicators excited at 488nm in primary screens. Fura-2 AM can be easily loaded into cells by passive incubation. Wavelength Maxima: Excitation 370nm, Emission 476nm
