INDO 1 pentasodium
INDO 1 pentasodium is a cell-impermeable, dual-emission ratiometric fluorescent calcium indicator with a KD·β value of 0.44 μM. INDO 1 pentasodium binds to intracellular free calcium ions and undergoes wavelength-dependent fluorescence changes. In the unbound state (free form) without Ca2+, its fluorescence emission peak is at 485 nm upon excitation with ultraviolet light (350 nm). When INDO 1 pentasodium binds to Ca2+ (bound state), the emission peak shifts to 405 nm (Ex = 350 nm; dual emission at Em= 405/485 nm).

Activité biologique
INDO 1 pentasodium enables accurate measurement of absolute cytoplasmic Ca2+ levels in R1-R6 photoreceptors of white-eyed Oregon wild-type Drosophila melanogaster[1].
INDO 1 pentasodium binds extensively to proteins isolated from rabbit ventricular myocytes[2].
INDO 1 pentasodium is a calcium-sensitive fluorescent dye used in glass capillaries, with an apparent KD·β value of 0.44 μM; as calcium concentration increases, its emission at 405 nm enhances while emission at 470 nm diminishes[3].
