MQAE (N-(Ethoxycarbonylmethyl)-6-methoxyquinolinium bromide) is an improved chloride indicator that has greater sensitivity to chloride (Ksv= 200M-1) than SPQ (Ksv=118 M-1) and higher fluorescence quantum yield. The ester group of MQAE may slowly hydrolyze inside cells, resulting in a change in its fluorescence response.

MQAE is white solid, and with molecular weight is 326.19. Abbkine supplies below price/size for your choice: $70/50 mg, $525/500 mg.

The N-(Ethoxycarbonylmethyl)-6-methoxyquinolinium bromide has below features:
• MQAE has high water solubility and membrane permeability.
• MQAE with bromide ion as a counteranion has fluorescence excitation at 350 nm and emission at 460 nm.
• The fluorescent intensity of MQAE decreases in proportion to the chloride increase in cells.
• Chloride ion concentrations less than 50 mM may be monitored without being affected by pH changes.
