Another application and fluorophore that we used was indo-1 for calcium imaging ().Indo-1 (Molecular Probes, Eugene, OR) is a ratiometric Ca 2+ indicator, which is the preferred dye, instead of fura-2, in systems (such as two-photon microscopy), where it is more practical to use a single laser for excitation (720 nm with a two-photon system) and monitor two emission wavelengths (453 and 405 nm).
The maximum imaging depth achievable for one-photon excitation is around 100 µm. In contrast, multiphoton microscopy takes advantage of multiphoton excitation with infrared light which has reduced scattering due to the longer wavelengths. This fact makes multiphoton microscopy ideal for deep tissue imaging of thick specimens and samples.
