Abstract

This invention relates to a method for analyzing a gene and an analysis device thereof which are suited to be used, for example, as a fully automatic gene analysis device or a fully automatic gene diagnostic device which can be simplified in structure, made compact in size and light in weight, and manufactured at a low cost and in which detection of various kinds of DNA can be conducted rapidly and with precision and analysis of a plurality of genes can be made simultaneously from different kinds of samples by restraining, as much as possible, the use of a valve in an analytic system, thereby preventing admixture of cross contamination. It relates to a gene analysis method comprising the steps of extracting a target nucleic acid from a biological sample (23) and amplifying a target DNA, thereafter, introducing a reaction eluent (L) containing a predetermined DNA into a stationary-phase DNA probe (53) having a predetermined temperature and arranged in series or in parallel and separating a DNA complementary to the stationary-phase DNA probe (53). The above-mentioned gene analysis method comprises a plurality of stationary-phase DNA probes (64 through 66) at least a part of which can be set to a temperature for forming a double strand of DNA to be tested and a reaction eluent containing the same or different kinds of DNA which have been amplified, is introduced into the stationary-phase DNA probes (64 through 66).
