MQAE

Introduction

MQAE is a 6-methoxyquinolinium derivative and is a fluorescent indicator for intracellular Cl^–. This dye detects the ion via diffusion-limited collisional quenching. MQAE has greater sensitivity to Cl^– and a higher fluorescence quantum yield than SPQ; consequently, it is currently the more widely used of the two indicators.
