  • Publication number: 20060003325
    Abstract: The present invention provides a nucleotide mutation detection method wherein primers having a nucleotide sequence complementary to part of the nucleic acids to be detected and also having a nucleotide sequence, which is complementary to the nucleotide sequence just upstream from a nucleotide site corresponding to the mutation site of the nucleotide sequence formed at the 3? end, added to the 5? end, are produced so that so that the nucleotide site corresponding to the mutation site of the nucleic acids to be detected including the nucleotide mutation is located within the nucleotide sequence formed at the 3? end after elongation; a target is produced by subjecting the primers to an elongation reaction using polymerase or Klenow enzyme; the target is then denatured to a single strand, and is subjected to a hybridization reaction with a probe that has the nucleotide complementary to the mutation site of the nucleic acids present in the 3? end region and then to a ligation reaction, whereby it is enable to dete

  • Publication number: 20050107956
    Abstract: The present invention relates to a concentration measuring method which includes selecting a calibration curve optimum for computing the concentration of a measurement target substance from a plurality of calibration curves based on an output from a reaction system containing the target substance and a reactant capable of reacting with the target substance, and computing the concentration of the target substance based on the optimum calibration curve and the output. Each of the calibration curves is prepared based on a plurality of outputs generated upon lapse of a same reaction time from a plurality of standard reaction systems each containing a standard reagent of a known different concentration and the reactant. The plurality of calibration curves differ from each other in reaction time based on which the calibration curves are prepared.
