  • Patent number: 9545630
    Abstract: Provided is a method for fabricating a microchip for nucleic acid amplification reaction that is capable of simple and highly accurate analysis. Provided is a method for fabricating a microchip for nucleic acid amplification reaction, the method including a solidification step of drying a reagent solution including at least a part of substances required for a nucleic acid amplification reaction, and a containment step of arranging the reagent solution including the solidified substance in wells that serve as a reaction site for a nucleic acid amplification reaction. In the microchip for nucleic acid amplification reaction fabricated by the fabrication method, since substances required for the nucleic acid amplification reaction are contained by being solidified, non-specific amplification is suppressed in a nucleic acid amplification reaction, which enables highly accurate analysis.

    Abstract: The present disclosure relates to a method and apparatus for separating nucleic acids. A carrier may include a porous microbead having cation-exchangeable groups attached to the surface of the porous microbead. Capturing chains modified with positively charged functional groups and having a base sequence complementary to a target nucleic acid chain sequence are immobilized on to the surface of the porous microbead. In various embodiments, capturing chains are immobilized on to the surface of the porous microbead through an ion exchange bond or a covalent bond with the cation-exchangeable groups of the porous microbead. In some cases, the porous microbead has a number of through pores adapted to permit a solution to pass rapidly through the through pores and a number of diffusive pores adapted to permit a solute of the solution to diffuse into the diffusive pores.
