    Product Description

    Di-4-ANEPPS is a potentiometric fluorescent dye that can be used to measure membrane potential.1 It displays absorption/emission maxima of 495/705 nm, respectively.2 The relative fluorescence changes proportionally to membrane potential at a rate of approximately 10% per 100 mV.1 Di-4-ANEPPS has been used to measure membrane potential in a variety of tissue and cell types as well as artificial membranes.1,2
