  • CAPILLARY ARRAY APPARATUS, METHOD OF MANUFACTURING THE SAME, AND ELECTROPHORESIS ANALYSIS METHOD
    Publication number: 20080302665
    Abstract: An electrophoresis analysis method and apparatus capable of maintaining high reliability upon a repeated use of the same gel. A heat transfer medium selected from the group consisting of solids, liquids and gels is filled in substantially all of the gaps between the electrode and each capillary. A hollow electrode into which a capillary is inserted has a plurality of retaining shapes such that the capillary can be fixed at the center of the electrode. The heat from the capillary can be efficiently dissipated via the electrode, and also the temperature increase in the capillary can be prevented. Further, temperature increases due to the heating of the capillaries during operation can be controlled and thereby thermal deterioration of the gel can be prevented.
    Type: Application
