| 摘要 |
The present invention provides a novel method for forming a self-assembly substance of probes making it possible to shorten a reaction time required for formation of a self-assembly substance and also to increase regions of probes available for detection of a target gene by previously preparing a plurality of dimer-probes and increasing the types. This method comprises the steps of: providing plural groups, wherein each group includes a pair of dimer forming probes containing a pair of oligonucleotides, each oligonucleotide having three regions of a 3' side region, a mid-region and a 5' side region, in which the mid-regions of the oligonucleotides have base sequences complementary to each other, and the 3' side regions and the 5' side regions of the oligonucleotides have base sequences not complementary to each other; hybridizing a plurality of pairs of the dimer forming probes of the plural groups; and forming a double-stranded self-assembly substance by self-assembly of the oligonucleotides.
