MQAE is a fluorescent chloride ion indicator that is more sensitive and selective than 36Cl and microelectrode-based methods for chloride measurement in cells. MQAE is a fluorescent indicator that is quenched via collision with chloride. The probe is suitable for detection of chloride concentrations in liposomes, reconstituted membranes or in extracellular medium. As a UV-excitable indicator, MEQ can be detected using an argon-ion laser for confocal microscopy and flow cytometry applications. MQAE has greater sensitivity than SPQ and higher fluorescence quantum yield. The ester group of MQAE may slowly hydrolyze inside cells, resulting in a change in its fluorescence response. Wavelength Maxima: Excitation 350nm, Emission 460nm
