  • Patent number: 10428372
    Abstract: A probe system for real-time quantitative and qualitative analysis of a biomaterial, and a reaction chamber with the probe system, and an analysis method thereof are provided. The probe system, which is included in the reaction chamber having an optically transmissive flat bottom surface and having a test sample accommodated therein, includes a target probe-reporter probe linker accommodated in the reaction chamber and including a target probe, which includes a sequence complementary to a target nucleic acid sequence to be detected, a first fluorophore and a first quencher, and a reporter probe linked to an end of the target probe and including a sequence non-complementary to the target nucleic acid sequence, and a capture probe included in a biochip formed on a bottom surface of the reaction chamber and including a complementary sequence hybridizable with the non-complementary sequence of the reporter probe, a second fluorophore and a second quencher.
    Type: Grant

  • Patent number: 10364459
    Abstract: A method of quantitatively and qualitatively analyzing a biomaterial in real-time, the method comprising preparing a device for detecting a biomaterial, feeding a complex of first and second probes, a forward primer, a reverse primer, a sample comprising deoxynucleotide triphosphate, a polymerase having exonuclease activity, and a sample comprising target genes, and a reaction solution comprising a buffer into the reaction container, performing polymerase chain reaction comprising denaturation of the target genes in the sample, hybridization of the target genes, the complex, and the forward and reverse primers in the sample, and elongation of the primers through the polymerase having exonuclease activity, allowing for elongation of the second probe on the third probe by the polymerase after hybridizing the released second probe and the third probe fixed to the biochip, detecting a first fluorescence signal by the first phosphor and a second fluorescence signal by the second phosphor.

  • Patent number: 9551038
    Abstract: Provided are a system for integrated analysis of a real-time polymerase chain reaction and a DNA chip and a method for integrated analysis using the same, and more particularly to an apparatus for integrated analysis of a real-time polymerase chain reaction and a DNA chip and a method for integrated analysis using the same. According to the method for integrated analysis of a biomaterial of the present invention, gene amplification proceeds and subsequently hybridization proceeds in a single reactor, thereby preventing contamination of the sample due to external factors, which may be caused while the sample is transferred for reaction, and automating a series of procedures such as injection of the sample, reaction of the biomaterial, and detection and analysis of results.
