    摘要： Accurate and sensitive sequencing in pyrosequencing is achieved by allowing complementary strand synthesis reaction to proceed homogeneously and completely in a short time while performing luminescence reaction for a sufficiently long time. DNA as a sequencing target is immobilized on the surface of a solid support. Nucleic acid substrates are injected from a dispenser to the support site where complementary strand synthesis is in turn performed rapidly and completely in a short time under a small reaction volume. Next, the support together with the product thereon is moved into a luminescence reaction solution where luminescence reaction is in turn performed. Thus, a DNA complementary strand synthesis reaction site and a luminescence reaction site are completely separated. The support surface is also washed by dipping the support in the luminescence reaction solution that contains a luminescence reagent and an enzyme that degrades redundant nucleic acid substrates.

    摘要： It is intended to provide a technique for amplifying, individually and in parallel, nucleic acids contained in a mixture of plural kinds of nucleic acid samples. The present invention provides a nucleic acid analysis method comprising amplification means, whereby amplification reaction is performed in a reaction solution comprising a homogeneous solvent and comprising at least plural template nucleic acids and solid phase carriers comprising one or more kinds of amplification probes immobilized on the surface, to prevent amplified products attributed to two or more template nucleic acids from being replicated in one solid phase carrier. According to the present invention, plural kinds of analyte nucleic acid samples in a mixed state can be amplified individually and in parallel. This method achieves one solid phase carrier-one nucleic acid. Therefore, a higher density of solid phase carriers with obtained amplified products is easily achieved, leading to improved throughput of amplified product analysis. Reactions in all the amplification reaction steps are performed under homogeneous solvent conditions. Therefore, the method of the present invention is performed by convenient procedures and as such, is suitable to automation.
