An electrophoresis device is used to separate a biological substance using a separation medium. A recovery hole configured to recover the separated target biological substance is formed in an electrophoresis device, the recovery hole is configured to be capable of accommodating a solvent that can suspend the target biological substance, a buffer tank configured to accommodate a buffer solution is provided below the recovery hole, and a membrane is disposed between the recovery hole and the buffer tank.

Electrophoresis device and biological substance recovery method

An electrophoresis method, system, and gel recover biological substances from the gel with high efficiency. The method uses an electrophoresis gel having an injection hole into which biological substances are injected and a recovery hole from which the biological substances are recovered. The electrophoresis method includes injecting the biological substances into the injection hole, and applying an electric field penetrating the injection and recovery holes. A vertical axis in a downward direction as a positive direction is set as an X-axis, an axis which is perpendicular to the X-axis is set as a Y-axis, and coordinates of a bottom of the recovery hole are set as (X, Y). The X coordinate Xof the bottom of the recovery hole satisfies X&#x3e;Xwhen the biological substance is electrophoresed to coordinates (X, Y) in the recovery hole from a bottom of the injection hole in the applying the electric field.
