Abstract
There are beforehand prepared a monomer having a reaction residue and a polynucleotide probe set comprising plural kinds of polynucleotide probes having a residue bonded to the reaction residue. The monomer is mixed with each kind of polynucleotide probes comprising any plural probes selected from the polynucleotide probe set. Each kind of the resultant mixtures is added to each of different small holes to make the mixture into gel matrix. Thus, a polynucleotide probe chip is produced. Sample DNA is forcibly migrated in the gels by electrophoresis. Laser light is projected onto the side face of the chip. The fluorescence emitted from the whole surface of the chip is collectively detected with a high-sensitive two-dimensional detector. Thus, the polynucleotide probe chip, holding various kinds of DNA probes, for detecting DNA can be provided. This chip has high hybridization-efficiency and makes high-sensitivity and high-speed DNA detection possible.
