Abstract

Official abstract text for this publication.

Provided is an electrophoresis device that, by electrophoresis, feeds a sample into capillaries and optically detects the sample, the electrophoresis device being provided with capillaries, a capillary head provided at the distal end of the capillaries, a phoretic medium-filled container used for electrophoresis and filled with a phoretic medium, a guide member that covers the side surface of the phoretic medium-filled container, a seal member that seals from below the phoretic medium filled in the phoretic medium-filled container, and a plunger that presses the seal member.

First claim

Opening claim text (preview).

The invention claimed is: 1. An electrophoresis method which is an analysis method using an analysis device including capillaries, a capillary head that is provided at a distal end of the capillaries, a phoretic medium container that is used for electrophoresis and filled with a phoretic medium, a liquid feeding mechanism that is provided with a plunger and feeds the phoretic medium in the phoretic medium container to the capillaries, wherein the phoretic medium container is provided with a syringe, a seal member that is disposed in the phoretic medium container separately from the plunger, seals the phoretic medium in the syringe from below and is operated within the syringe by pressing the seal member from below with the plunger, and a lid portion including a rubber stopper that seals an upper part of the syringe, the method comprising: breaking through the rubber stopper with the capillary head; and pressing the lid portion using the capillary head at a time of pressing the seal member from below with the plunger. 2. The electrophoresis method according to claim 1 , further comprising: pushing the seal member toward a bottom end of the phoretic medium container due to internal pressure of the phoretic medium container after releasing a pressing force of the plunger to the seal member. 3. The electrophoresis method according to claim 1 , wherein the lid portion further includes a cap and a film, the rubber stopper is disposed between the cap and the syringe, and the cap is disposed between the rubber stopper and the film. 4. The electrophoresis method according to claim 2 , further comprising: pulling out the capillary head from the phoretic medium container.
