Application Nonfluorescent Ca2+ ionophore that can be used to calibrate the quantitation of cytoplasmic free Ca2+ with fluorescent probes. Bromo-A23187, a nonfluorescent ionophore, has been used in photolysis of a caged-Ca2+ compound and in [Ca2+]i elevation protocols1. It can be used to calibrate the quantitation of cytoplasmic free Ca2+ with fluorescent probes. Other Notes In biological environment, bromo-A23187 has a higher selectivity for Ca2+ over Mg2+ than A231872 Biochem/physiol Actions Ionophores disrupt transmembrane ion concentration gradients which are required for proper functioning and survival of microorganisms. An ionophore, such as Bromo-A23187, increases the permeability of biological membranes to calcium.
Application Nonfluorescent Ca2+ ionophore that can be used to calibrate the quantitation of cytoplasmic free Ca2+ with fluorescent probes. Biochem/physiol Actions Ca2+ ionophore that is used to potentiate responses to NMDA, but not quisqualate. Other Notes Analog of calcium ionophore A23187
