DNA detector and DNA detection method

Abstract

A method for determining a DNA sequence includes providing a sample which contains first DNA fragments having adenines at an end and labeled by first fluorophores, second DNA fragments having thymines at an end and labeled by second fluorophores, third DNA fragments having cytosines at an end and labeled by third fluorophores, and fourth DNA fragments having guanines at an end and labeled by fourth fluorophores, wherein each of the first to fourth fluorophores is different. The sample is supplied into a capillary and the sample is made to migrate in the capillary. A sheath flow is formed around an end of the capillary where the sample migrates, a light is irradiated into the sheath flow to excite the fluorophores. Fluorescence emitted from the fluorophores is detected and the fluorophores are identified.
