DETAILS

Description (English)

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.
