Bromo-A23187: a nonfluorescent calcium ionophore for use with fluorescent probes.
4-Bromo-A23187, a halogenated analog of the widely studied divalent cation ionophore A23187, is a nonfluorescent Ca2+ ionophore suitable for use in the calibration of cytoplasmic free Ca2+ by fluorescent probes. Br-A23187 is shown to saturate Ca2+ sites in quin-2-loaded rat thymic lymphocytes in a manner essentially identical to ionomycin.
