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. White solid soluble in water and DMSO Store at 4C and protect from light, especially in solution &lamba,Ex/lambdaEm= 350/460nm epsilon (344 nm, H2O) = 2,800 C14H16BrNO3 MW: 326.19 [162558-52-3]
