INDO 1 pentasodium is a ratiometric, free calcium ion Ca2+ fluorescent indicator that can quantitatively monitor dynamic changes in intracellular free Ca2+ concentrations. When unbound to Ca2+ free state , INDO 1 pentasodium exhibits a peak emission wavelength of 485 nm under UV excitation 350 nm . Upon binding to Ca2+ bound state , the emission peak shifts to 405 nm. INDO 1 pentasodium is highly photolabile and susceptible to photobleaching, and its emission spectrum may overlap with the autofluorescence of NADH.
