Background:

Indo-1 is a ratiometric fluorescent calcium indicator. It is ideal for analyses using flow cytometry, as it uses a single excitation source, typically 349-364 nm light from an argon-ion laser. The emission maximum shifts from 475-485 nm without calcium to 400-410 nm when indo-1 binds calcium. Indo-1 is prone to photobleaching, which limits its usefulness in methods involving microscopy.
