    • The present invention relates to the detection of a target nucleic acid sequence by a POCH (PO Cleavage and Hybridization) assay on a solid substrate. The present invention detects the target nucleic acid sequence by use of in which the PO (Probing Oligonucleotide) hybridized with the target nucleic acid sequence is cleaved and the cleavage of the PO is detected by hybridization with the CO (Capturing Oligonucleotide). In the present invention, an uncleaved PO is hybridized with the CO immobilized onto the solid substrate. The designs of the PO and the CO are convenient and the optimization of reaction conditions is routinely easy in the present invention. Where the detection of signal on the solid substrate is continuously performed along with repetition of cleavage of the POs in the present invention, the number of the POs cleaved is increased upon the repetition number of the cleavage reaction and the signal is changed in parallel with the number of the POs cleaved. Then, the target nucleic acid sequence can be detected in a real-time manner. In contrast, the change of the signal is not observed in the absence of the target nucleic acid sequence.
    • 本发明涉及通过在固体基质上的POCH(PO切割和杂交)测定来检测靶核酸序列。 本发明通过使用其中与靶核酸序列杂交的PO(探针寡核苷酸)被切割并且通过与CO(捕获寡核苷酸)杂交来检测PO的切割来检测靶核酸序列。 在本发明中,未固定的PO与固定在固体基质上的CO杂交。 PO和CO的设计是方便的,本发明中反应条件的优化通常是容易的。 当在本发明中连续进行固体基质上信号的检测以及POs裂解的重复时,裂解反应的重复次数增加了裂解的PO的数量,并且信号与 已劈开的采购订单数量。 然后,可以实时检测目标核酸序列。 相反,在不存在靶核酸序列的情况下没有观察到信号的变化。
