ISOELECTRIC FOCUSING APPARATUS AND ISOELECTRIC FOCUSING METHOD

摘要

The present invention prevents ionic contaminants from being deposited on an electrode in contact with a gel in isoelectric focusing and obtains clear electrophoresis results. An isoelectric focusing apparatus (1) is provided with a gel (2) having a pH gradient formed therein and first and second electrodes (4, 3) for applying a voltage to the gel (2). The first electrode (4) is in contact with the gel (2), and the isoelectric focusing apparatus (1) is further provided with a solvent holding part (6) for holding a solvent and bringing the solvent into contact with the first electrode (4) and gel (2).
