    摘要: This invention provides a method of genetic testing that enables testing of a plurality of variation sites (SNPs) in a cost-effective and simple manner, allowing realization of genetic diagnosis in clinical settings. The SNP type of the nucleic acid sample is evaluated by: allowing a nucleic acid sample having an anchor sequence at its 5′ end to hybridize to a support having, immobilized on its surface, a probe containing a sequence that is complementary to the target sequence (the SNP region); extending a complementary strand from the probe utilizing the nucleic acid sample as a template; dissociating and removing the nucleic acid sample from the extended probe; extending a complementary strand using the extended probe as a template and a primer having a sequence identical to the anchor sequence; and detecting pyrophosphoric acid generated via the primer extension, based on bioluminescence.

    摘要: A simple and highly accurate method for detecting the presence or absence of gene mutation and methylated cytosine in CpG dinucleotide that are contained in a target sequence derived from an analysis sample is provided. Features of the method for nucleic acid analysis include cleaving one or more noncomplementary sites in a double-stranded nucleic acid sample by a single strand-specific endonuclease, hybridizing at least one of the nucleic acid fragments obtained to a probe containing a nucleotide sequence that is partially or totally identical to either one strand of the double-stranded nucleic acid sample, allowing an extension reaction to proceed from the nucleic acid fragment hybridized to the probe, and optically detecting pyrophosphate generated by the extension reaction, thereby judging the presence or absence of at least a noncomplementary site in the double-stranded nucleic acid sample.

    摘要: A DNA analyzing method which bonds a first oligomer of known base sequence to a DNA fragment obtained by digesting a DNA sample with a restrictive enzyme. The oligomer and DNA fragment are hybridized to other oligomers which have the sequences of all combinations of the types of bases within the length of several bases following the known base sequence. The presence or absence of hybridization or complementary DNA strand extension is determined and identifies the DNA fragment terminal sequence from this result. The DNA fragments are then fractionated and analyzed to determine the sequence. This DNA analyzing method provides an effective analysis of mixtures of long DNAs or DNA fragments.

    摘要: A method for examining nucleotide sequences of a sample includes adding a group of primers of multiple species to a solution containing the sample and simultaneously synthesizing complementary strands at each of the multiple regions containing the nucleotide sequences; designing the DNA probes with specific sequences elongate the complementary strands by the presence or absence of mutations in the nucleotide sequences, wherein the same number of such DNA probes and the nucleotide sequences are used for complementary strand synthesis; using the nucleotide sequences or their complementary sequences as a template to convert pyrophosphate produced during the elongation reaction to ATP which then reacts with chemiluminescent substrates to develop luminescence to be detected. According to the method, sensitivity is greatly increased by amplification of the amount of pyrophosphate produced in synthesis of the complementary strands without amplifying the copies of nucleotide sequences.
