Ion and pH indicators
Ion and pH indicators are fluorescent compounds that undergo shifts in fluorescence spectra in response to changes in ion concentrations. Many ion indicators are available as membrane-permeable AM ester derivatives, which are hydrolyzed by cytoplasmic esterase enzymes to generate functional free acid indicator dyes.
