  • Patent number: 9540681
    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.

  • Publication number: 20160376643
    Abstract: The present invention relates to a method for quantifying a target nucleic acid sequence by use of a common internal control. The present invention allows to determine an absolute initial amount of a target nucleic acid sequence with no use of a standard curve. The present invention amplifies not only a control reaction mixture comprising a known-amount standard and an internal control but also a sample reaction mixture comprising an internal control identical to the internal control in the control reaction mixture and the target nucleic acid sequence to be quantified. In the present invention, a relative ratio of the amount of the standard and the amount of the target nucleic acid sequence is calculated by using the internal control and then an initial amount of the target nucleic acid sequence is determined by using a known amount of the standard.

  • Patent number: 9518289
    Abstract: The present invention relates to a novel method for detection of target nucleic acid sequences by cyclic exonucleolytic reactions (CER) or exonucleolytic reactions (ER) using single-labeled immobilized probes on a solid phase. The present invention enables to detect target nucleic acid sequences on a solid phase using single-labeled systems. Comparing with multiple-labeled systems such as dual labeling, the present invention using single-labeled probes has excellent advantages in light of convenience and cost effectiveness in probe design and preparation. Furthermore, the measurement of changes of the signal decrease during reactions is responsible for more accurate qualitative and quantitative analysis of target nucleic acid sequences.

  • Publication number: 20160273041
    Abstract: The present invention is generally drawn to a novel method for determining a SNP (single nucleotide polymorphism) genotype using a PTO-SNV (Probing and Tagging Oligonucleotide for Single Nucleotide Variation). The present invention provides novel protocols for SNP genotyping in which only one allele-specific oligonucleotide permits in a SNP genotyping reaction to determine whether a target nucleic acid sequence to be analyzed is homozygous or heterozygous for the SNP allele of interest or has no SNP allele of interest.

  • Publication number: 20160258007
    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.

    Abstract: The present invention relates to the detection of a target nucleic acid sequence by a PCE-IH (PTO Cleavage and Extension-Dependent Immobilized Oligonucleotide Hybridization) assay on a solid phase. The present invention firstly hybridizes the PTO with a target nucleic acid sequence, forms the extended strand in a target-dependent manner by using the CTO having artificially selected sequence as templates and finally hybridizes the extended strand with the IO immobilized on a solid phase. In other words, the present invention employs a series of reactions including PTO hybridization and cleavage, CTO hybridization and extension and IO hybridization, which is responsible for the highly enhanced specificity of the present invention.

  • Patent number: 9328377
    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.

  • Publication number: 20160060690
    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?-tagging 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 PTO Cleavage and Extension-Dependent Signaling Oligonucleotide Cleavage assay (PCE-SC assay). The present invention is carried out in such a manner that the extended strand is produced on the CTO having arbitrary sequences as templates depending on the presence of target nucleic acid sequences and in turn the SO as probes is hybridized with the extended strand to give signal. The present invention employs a series of reactions including PTO hybridization and cleavage, CTO hybridization and extension, and SO hybridization and cleavage, which is responsible for the highly enhanced specificity of the present invention.

  • Publication number: 20140073534
    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.

  • Patent number: 8669741
    Abstract: A battery management system (BMS) manages a battery for a hybrid vehicle including an engine control unit and a motor generator controlled by the engine control unit and connected to a battery including at least one battery pack, each pack including a plurality of battery cells. The BMS includes a sensor and an MCU unit. The sensor detects temperature, current, and open circuit voltage (OCV) of the battery. The MCU receives the detected temperature, current, and OCV, calculates a key-off time period which is a period between a time point when a battery key-on state ends and a time point when a subsequent battery key-on state begins, calculates an OCV error range corresponding to an SOC error range detected at the key-off time point, and infers an initial SOC of the battery.
