Indo-Hi (Ca2+bound)

Indo-Hi (Ca2+bound) (Ex-Max 329 nm/Em-Max 401 nm)

Indo-1, AM is a ratiometric calcium indicator optimally excited by a 355nm UV laser or excitation source. After Indo-1, AM is loaded into live cells, it is hydrolyzed and available to bind cytoplasmic Ca2+. Probe bound to Ca2+ emit at ~400nm, while probe unbound to Ca2+ emits at ~475nm. Because of these unique spectral characteristics, it's the preferred calcium indicator for flow cytometry and is often frequently used in fluorescence live-cell microscopy.
