  • Publication number: 20110159482
    Abstract: The present invention discloses a method for simultaneously detecting multiple small nucleic acids, which comprises steps: mixing a specimen, fluorescent probes, and bridge nucleic acids having different lengths to form a tested liquid; hybridizing the mixed short nucleic acid molecules, probes and bridge nucleic acids; adding ligases to enable the ligations of the short nucleic acid molecules and the fluorescent probes with the bridge nucleic acids being the templates; injecting the tested liquid into a capillary, and applying a voltage to the capillary to generate an electrophoresis effect and separate the hybridization products; and using laser to induce different fluorescent rays from different reaction products, and measuring the fluorescent rays, whereby the present invention can simultaneously detect multiple types of short nucleic acid molecules in a single capillary.

  • Publication number: 20100317029
    Abstract: The present invention discloses a nasopharyngeal cancer malignancy biomarker and a method thereof, wherein relative TP expression is used to evaluate the malignancy of nasopharyngeal cancer. The biomarker of the present invention assists the currently-existing inspections to find out cancer in the early stage and achieve early diagnosis and early therapy. The present invention also functions as an effective indicator to monitor the metastasis and relapse of nasopharyngeal cancer.

  • Publication number: 20100193357
    Abstract: The present invention discloses a quantitative analysis method for microRNAs, wherein a fluorescence-labeled DNA probe, which is equinumerous and completely complementary to a microRNA, hybridize with the microRNA. The products of hybridization include the fluorescence-labeled DNA probe containing 22 nucleotides and the probe-microRNA duplex containing 22 base pairs. The products of hybridization is introduced into a capillary by the pressure difference between two ends of the capillary and the siphon effect and separated by electrophoresis. A laser is used to induce fluorescence from the products of hybridization. Then, the intensities of fluorescence are measured and analyzed.
