An automated analyzer includes a reagent dispensing probe that dispenses a reagent to a reaction vessel, a sample dispensing probe that dispenses a sample to the reaction vessel, a stirring rod that stirs a sample and a reagent in the reaction vessel, and a storage unit that stores special washing information including information about a condition for performing special washing to prevent sample carryover and a washing method. The automated analyzer further includes: a determination unit that determines whether the special washing is required based on information about the sample dispensed by the sample dispensing probe and the special washing information; and a controller that causes the reagent dispensing probe to dispense a wash liquid to the reaction vessel and causes the stirring rod to stir the wash liquid in the reaction vessel based on the special washing information, when the special washing is performed.

A detection system of a test substance, includes: a magnetic body that is modified by a first substance capable of being bound to the test substance at a first binding site of the test substance; a marker that is modified by a second substance capable of being bound to the test substance at a second binding site of the test substance, the second coupling site being a different site from the first binding site; a development medium that has a flow passage into which liquid, in which the magnetic body and the marker is dispersed, flows due to a capillary phenomenon, the development medium having a detection position for detecting the marker in a portion of the flow passage, the development medium having light transparency at least in the detection position; and a magnetic force generating portion that is equipped in the development medium.

Detection system of test substance

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&#x2032; 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&#x2032; 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&#x2032; end region and then to a ligation reaction, whereby it is enable to determine and assay a nucleotide located at a specific position in a nucleotide sequence of DNA or RNA and to analyze rapidly a variety of mutations including single nucleotide mutations, short nucleotide tandem repeat mutations, nucleotide deletion mutations, nucleotide insertion mutations, translocation mutations and so on.

Method of detecting nucleotide mutations

A concentration measuring method 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.
