Glass capillary array for fluorescence analysis and manufacturing method thereof

摘要

A glass capillary array for fluorescence analysis is provided which is capable of preventing reduction of the transmittance of a laser beam through the glass capillaries during electrophoretic DNA fluorescence analysis, and a method of manufacturing the glass capillary array. The glass capillary array for fluorescence analysis is comprised of a plurality of glass capillaries each having a rectangular cross section and having an internal hole formed therein, and arranged in a row along a direction of irradiation of a laser beam for fluorescence analysis. The glass capillary array has a fluorescence analysis section comprising a portion of each of the glass capillaries positioned in a region including an optical axis of the laser beam and a vicinity thereof, and the glass capillaries are joined together substantially into a single body using a transparent material in at least the fluorescence analysis section.
