  • Patent number: 10731203
    Abstract: The present invention relates to the detection of a target nucleic acid sequence by a PCE-SH (PTO Cleavage and Extension-Dependent Signaling Oligonucleotide Hybridization) assay. The present invention does not use probes to be hybridized with target nucleic acid sequences for providing target signals. Interestingly, the present invention uses probes (signaling oligonucleotides) to be hybridized with the extended strand formed in a target-dependent manner in which the extended strand is synthesized using the CTO artificially selected as templates.

  • Publication number: 20200152294
    Abstract: The present invention relates to a method for calibrating a data set of a target analyte in a sample using an analyte-in-susceptible signal value, wherein the analyte-insusceptible signal value is provided by a background-representing signal value of the data set or by a total signal change value of a standard data set. The present method is very convenient and effective in removing the inter- and intra-instrument signal variations of data sets. Furthermore, since the present method can be configured in software, the instant method is capable of being applied universally to various analytical instruments (e.g., a real-time PCR instrument) regardless of manufacturer. Accordingly, the method by the present invention would be very useful in diagnostic data analysis.

  • Publication number: 20200087718
    Abstract: The present invention relates to the detection of a target nucleic acid sequence by a PTOCE (PTO Cleavage and Extension) assay. The present invention detects a target nucleic acid sequence in which the PTO (Probing and Tagging Oligonucleotide) hybridized with the target nucleic acid sequence is cleaved to release a fragment and the fragment is hybridized with the CTO (Capturing and Templating Oligonucleotide) to form an extended duplex, followed by detecting the presence of the extended duplex. The extended duplex provides signals (generation, increase, extinguishment or decrease of signals) from labels indicating the presence of the extended duplex and has adjustable Tm value, which are well adoptable for detection of the presence of the target nucleic acid sequence.
