    摘要: An RNA separation method includes injecting a reaction solution into a reaction region which contains a covalent linking of specific RNA probe for hybridizing with the reaction solution; adjusting a moderate hybridization temperature in the reaction region; moving the remainder of the reaction solution to a transition region by using a pneumatic actuator; adding a buffer solution to the reaction region, and heating the reaction region to a moderate denature temperature by a heating apparatus; moving a waste solution which is product produced from the reaction region after denature to a waste region by using the pneumatic actuator; and moving the remainder solution back to the reaction region by the pneumatic actuator.

    摘要: The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

    摘要: A method for the analysis of DNA sequences and PCR products comprises the steps of constructing an oligonucleotide-labeled bead set, and labeled complementary probe, and exposing the bead set and probe to a DNA fragment or PCR product under hybridizing conditions and analyzing the combined sample/bead set by flow cytometry. Flow cytometric measurements are used to classify beads within an exposed bead set to determine the presence of identical or nonidentical sequences within the test sample. The inventive technology enables the rapid analysis of DNA sequences and detection of point mutations, deletions and/or inversions while also reducing the cost and time for performing genetic assays.
