Abstract

The present disclosure pertains to a method for detecting multiple target nucleic acids by a single type of label alone in a single reaction vessel by using multiple detection temperatures, which is characterized by providing a signal change dependent on the presence of a corresponding target nucleic acid at a corresponding detection temperature of each of the target nucleic acids. The conventional techniques using a single type of label is subjected to melting analysis after target amplification so as to detect multiple target nucleic acids. In contrast, the present method does not require melting curve analysis after target amplification, even using a single type of label, and thus can remarkably reduce the analysis time.

Abstract

The present invention relates to a computer-implemented method for providing a nucleic acid sequence data set for the design of an oligonucleotide used to detect a target nucleic acid molecule of an organism of interest. In the present invention, nucleic acid sequence data retrieved by synonyms for a target nucleic acid molecule are sorted according to the taxonomic name and/or taxonomic identification (ID); taxonomic representative sequences are selected among nucleic acid sequence data having the same taxonomic name and/or taxonomic ID; and the selected taxonomic representative sequences are grouped according to the homology to select a group representative sequence in each group; and then nucleic acid sequence data having a homology of a predetermined value or more with the group representative sequence are provided. As a result, it was confirmed that multiple target nucleic acid sequences for the target nucleic acid molecule were retrieved without omission and the alignment results of the retrieved multiple target nucleic acid sequences were properly formed so as to be referred to in the design of oligonucleotides.

Abstract

The present invention relates to the detection of a target nucleic acid sequence by a PCE-NH (PTO Cleavage and Extension-Dependent Non-Hybridization) assay. The present invention adopts the occurrence of the inhibition of the hybridization between the HO with the CTO by the formation of the target-dependent extended duplex. Therefore, the present invention may detect target sequences even when the HO is not cleaved. In this regard, the design of the 5'-taggeing portion of PTO, CTO and HO sequences may be readily performed and the conditions for reactions may be also easily established. In addition, the detection of the hybrid between the CTO and the HO may be performed in a different vessel from that for the extension of the CTO.

Abstract

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.

Abstract

The present invention relates to the detection of a target nucleic acid sequence in a real-time manner using a target signal generating primer (TSG primer) having dual interactive labels. The present invention allows for both target amplification and signal amplification by introducing dual interactive labels into a primer used in PCR reactions, ensuring real-time target detection by PCR reactions without the use of complicated oligonucleotides. The present invention could be free from the troublesome matters and shortcomings associated with conventional real-time PCR methods. The present invention allows for successful real-time target detection by using only a labeled primer. Also, the present invention can obtain strong signals indicative of the presence of target nucleic acid sequences in both a liquid phase and solid phase.

Abstract

The present invention relates to the detection of a target nucleic acid sequence using a target hybridization and detection primer (THD primer). The present invention allows for both a target amplification and a signal amplification by introducing a label into a primer used in PCR reactions, ensuring a real-time target detection by PCR reaction by no use of complicated oligonucleotides. The present invention could completely be free from the troublesome matters and shortcomings associated with conventional real-time PCR methods. The present invention allows for successful real-time target detection by using only a labeled primer. This feature makes it possible that the present invention exhibits excellent real-time target detection in multiplex manner.

Abstract

The present invention relates to a target discriminative probe (TD probe) and its uses or applications. The TD probe is hybridized with a target nucleic acid sequence through both of the 5'-second hybridization portion and the 3'-first hybridization portion. When the TD probe is hybridized with a non-target nucleic acid sequence, both the 5'-second hybridization portion and the separation portion are not hybridized with the non-target nucleic acid sequence such that both portions form a single strand due to its low Tm value. As such, the TD probe exhibits distinctly different hybridization patterns for each of the target and the non-target nucleic acid sequence, discriminating the target nucleic acid sequence from the non-target nucleic acid sequence with much higher specificity.

Abstract

The present invention relates to various processes by a template-dependent extension reaction using a dual specificity oligonucleotide and a dual specificity oligonucleotide composed of three different Tm portions therefor. Demonstrated in the present invention are the features of the dual specificity oligonucleotide, which are high hybridization specificity and mismatch tolerance.
