Glass capillary for DNA analysis and manufacturing method thereof, and DNA analyzer that uses the glass capillary

摘要

A glass capillary for DNA analysis is provided, which allows the DNA detection efficiency of a DNA analyzer that uses electrophoresis to be increased, and allows the DNA analyzer to have a simple structure. A glass capillary for DNA analysis has an internal hole, and each of the glass capillary and the internal hole has a rectangular cross section. Since the glass capillary and the internal hole each have a rectangular cross section, scattering of the laser beam at the surfaces of the glass capillary can be prevented and hence the transmittance of the laser beam can be increased. As a result, the detection efficiency of the electrophoretic DNA analyzer can be increased, and moreover the analyzer can be given a simple structure.
