- the method for detecting a target nucleic acid according to the present invention uses the solid phase for detection according to the present invention, and a set of probes on the solid phase for detection is used as a target nucleic acid.
- the hybridized product obtained by continuously hybridizing with a specific polynucleotide sequence and binding between the above two types of probes is detected by a ligase reaction of the obtained hybridized product (complex).

Therefore, when the target nucleic acid is removed by alkali treatment or the like after the ligase reaction, the probes are not linked to each other, and the respective ends are present. That is, one set of probes returns to the initial state.
- the present invention by detecting the obtained conjugate by various means, it is possible to know that the ligase reaction has occurred, and therefore to know the presence of the target nucleic acid. In this case, since the ligase reaction has extremely high specificity, it is possible to reduce the degree of false recognition to an extremely low level.

Therefore, for example, when exonuclease I is reacted here, the probe is digested (hydrolyzed) from the 3 'end of one probe. On the other hand, there is no 3 'end in the conjugate, and the probe is not digested even if exonuclease I is reacted there.

There is a method to detect a closed padlock probe. If necessary, the procedure can be repeated to add multiple padlock probes to amplify the reaction.

To maintain a specific position, a specific interaction occurs, and by detecting the specific interaction, the presence of the above-mentioned conjugate can be known.

At all locations, hybridize the target nucleic acid and wash away excess sample. Further, when a ligase-based binding reaction is performed at all positions, a conjugate is formed only when the corresponding specific polynucleotide sequence is present. In Fig. 8, they are 1, 3, and 5. Thereafter, as a means for detecting the obtained conjugate, various methods described above can be used. From the position where the presence of the conjugate is confirmed, a plurality of target nucleic acids present in the test sample are detected.
