Development of the Electrochemical Separation/Detection System for Proteins Using the Oil/Water Interface

在含有某些阴离子表面活性剂的油相和含有蛋白质的水相（pH = 3.4）之间的界面处，蛋白质的吸附通过与表面活性剂的络合而被促进。该反应依赖于油/水界面的电位差，并且在过量表面活性剂存在下，流过界面的电流与蛋白质浓度成比例，这表明蛋白质的定性和定量分析的可能性。基于这样的测量原理，我们可以开发一种蛋白质的流动分离/检测系统。

At the interface between an oil phase containing certain anionic surfactants and an aqueous phase (pH〓3.4) containing proteins, the adsorption of the proteins is facilitated by complexation with the surfactants. This reaction is dependent on the potential difference of the oil/water interface, and the electric current flowing through the interface is proportional to the protein concentration in the presence of excess surfactant, suggesting the possibility of qualitative and quantitative analyses of proteins. Based on such measurement principles, we could develop a flow separation/detection system for proteins.
