Outline of Final Research Achievements

In this study, we developed a high-throughput platform for analyses of ion channel functions. A cell membrane model was artificially reconstructed on a microchip, in which we optimized the efficiency and reproducibility of the membrane formation and integrated the number of the membrane on a single chip. Accordingly, we examined reconstitution techniques of ion channels into the membrane on the chip, and finally verified the developed platform using functional assays of drug-target ion channels. The results demonstrated the feasibility of our platform, especially for precise ion channel analyses with a single-molecule level. Based on the developed technologies, we continuously improve the performance of the platform, hoping for practical use in drug screening of ion channels.
