PROBLEM TO BE SOLVED: To provide a probe array for detecting various kinds of DNAs in which various kinds of arbitrary DNA probes are immobilized. SOLUTION: A probe array 4 in which particles (probe particles) 1 on which various probes 2 are fixed are arranged in a predetermined order is used. A plurality of capillaries or grooves filled with each probe particle are arranged in parallel, and one of each particle is injected from each capillary or groove into another capillary or groove, and various probe particles 1 Are always arranged in a fixed order to create a probe array 4. By bonding various kinds of probes to particles with different particle sizes, Simultaneous measurement of many types of fluorescently labeled DNA. [Effect] An array in which various types of DNA probes are immobilized can be easily prepared. |
