A-23187 Free Acid
Descrition & Target
A-23187, also known as Calcimycin or Calcium Ionophore III, is a calcium ionophore that rapidly equilibrates intracellular and extracellular calcium concentrations. It is commonly used for <i>in situ</i> calibrations of fluorescent calcium indicators. The ionophore allows Mn<sup>2 </sup> to enter the cells and quench intracellular fluorescence of calcium indicators.

Also see 4-bromo A-23187. Because 4-bromo A-23187 is nonfluorescent, it is preferred over the blue fluorescent A-23187 for calibrations of UV-excited Ca<sup>2 </sup> indicators such as Indo-1 and Fura-2 in order to keep background fluorescence to a minimum.
