There is used at least one probe array obtained by arraying particles having various probes, respectively, fixed thereon (probe particles) in a definite order in a holder. A plurality of capillaries or grooves packed with various kinds, respectively, of probe particles are arrayed in parallel, and one of particles contained in each capillary or groove is injected into another capillary or groove to produce a probe array in which the various kinds of probe particles are arrayed in a constant and definite order. Various fluorophore-labeled DNA's are measured at the same time by attaching various probes to particles, respectively, of different sizes. A probe array composed of various fixed DNA probes can easily be produced, and there can be provided a probe array for detecting various DNA's which is composed of various fixed arbitrary DNA probes. |
