  • Patent number: 7183056
    Abstract: The present invention is directed to an improved multiplex PCR method for obtaining at least two PCR products from one PCR solution. In the multiplex PCR method for having at least two DNA amplified products from a sample positioned in a PCR equipment, the object of the present invention is to provide a novel multiplex PCR method characterized in that a primer annealing temperature and an extension time be changed per cycle with constant periods. When a multiplex PCR is performed in accordance with the present invention, limitations in determining PCR conditions due to a various sizes of PCR products or dimers caused by primers can be eliminated, and time and efforts required for determining the PCR conditions to various samples can also be reduced. Further, not only refined DNAs like cDNA, genomic DNA, vector, etc, but blood can be directly used as a multiplex PCR sample, and PCR amplification reaction can be performed even with a sample having the smallest amounts.

  • Publication number: 20040110214
    Abstract: The present invention provides a chip for detecting DNA and method for detecting DNA using the same. In the chip according to the present invention, a double strand formed by hybridization of signaling DNA and probe DNA is fixed to an electrode, wherein the signaling DNA and probe DNA are complementary each other and either of the two is complementary to sequence of a target DNA, and the complementarity between the target DNA, and the signaling DNA and the probe DNA is different, and electrochemically active compound is bonded to the signaling DNA. Further, the method for detecting DNA according to the present invention induces competitive reaction for performing hybridization of the probe DNA and the signaling DNA, and detects the target DNA by measuring change in an electrochemical signal of the signaling DNA.
