発明の名称 (英語) PLANAR PATCH CLAMP DEVICE AND PLANAR PATCH CLAMP SYSTEM NEW
発明の概要(英語) A planar patch clamp device comprising: an electrically non-conductive substrate (2) having a through-hole (3) which passes liquid yet does not pass cells in a cell arrangement region (4); a first liquid reservoir unit (6) for holding a first electroconductive liquid, the first liquid reservoir unit (6) being provided so as to allow communication with the through-hole (3) on a first surface (2S) of the substrate (2); a first electrode unit (7) arranged so as to allow electrical conductivity with the first liquid reservoir unit (6); a second liquid reservoir unit (6') for holding a second electroconductive liquid, the second liquid reservoir unit (6) being provided so as to allow communication with the through-hole (3) on a second surface (2S') of the substrate (2); a second electrode unit (7') arranged so as to allow electrical conductivity with the first liquid reservoir unit (6); a liquid feed channel (8) for feeding the second electroconductive liquid to the second liquid reservoir unit (6'); a liquid discharge channel (9) for discharging the second electroconductive liquid from the second liquid reservoir unit (6'); and a valve (10) disposed in the liquid feed channel (8) and/or the liquid discharge channel (9), the valve (10) being capable of permitting or stopping the distribution of the second electroconductive liquid, and permitting or stopping electrical conductivity with the second liquid reservoir unit (6') and the second electrode unit (7').
