| 摘要 |
The present invention relates to an apparatus for detecting nucleic acid molecules such as target DNA molecules and mRNA molecules by using a DNA probe, and provides a DNA capillary, comprising a fluid passageway formed of a cylindrical capillary made of glass, a plurality of independent probe regions formed in the inner wall of the fluid passageway, and DNA probes each immobilized in the probe region, the immobilized DNA probes differing from each other. For performing the measurement, a sample is introduced through an open portion into the capillary so as to perform reaction and, then, fluorimetry.
