  • Patent number: 11915796
    Abstract: The present invention relates to a method for calibrating a data set of a target analyte in a sample, wherein a normalization coefficient for calibrating the data set is provided by using a reference value, a reference cycle and the data set, and the calibrated data set is obtained by applying the normalization coefficient to the signal values of the data set. The present method is very 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.

  • Patent number: 11447814
    Abstract: The present invention relates to the detection of a target nucleic acid sequence from a DNA or a mixture of nucleic acids by a PCE-hCTO (PTO Cleavage and Extension using hCTO) assay on a solid phase. According to the present invention, the extended duplex is formed in a liquid phase in a target-dependent manner and then its presence is detected on a solid phase. Since hCTO is not immobilized onto a solid phase, the extended duplex is more effectively formed in a liquid phase.

  • Publication number: 20220213535
    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.
