(E)-1-Ethyl-2-((1-ethylquinolin-2(1H)-ylide ne)methyl)quinolin-1-ium iodide

 Functional dyes such as membrane potential monitoring and cell tracking are dyes used in medical research and cell culture. After it enters the cell membrane, the dye diffuses on the entire cell membrane, and the entire cell membrane can be stained at the optimal concentration. Before the dye enters the cell membrane, the fluorescence is very weak. When combined with the cell membrane, the fluorescence intensity is greatly enhanced. This type of dye has a high quenching constant and excited state lifetime.Functional dyes include: JC-1, Di-8-ANEPPS, NeurotransRed, TMA-DPH, Dio, Dil, Cyanine, Department of cyanine and other dyes used to monitor membrane potential and cell tracking.
