Abstract: To provide an abnormality detection apparatus for resolver which can determine the abnormality of at least the first system, even if the period of the excitation AC voltage of the first system and the period of the excitation AC voltage of the second system are different periods, and the magnetic interference between systems occurs. An abnormality detection apparatus for resolver applies an AC voltage of a first period to a first system excitation winding; applies an AC voltage of a second period different from the first period to a second system excitation winding; calculates a first system square sum which is a sum of square values of the detection values of output signals of first system two output windings after the second period component reduction processing: and determines abnormality of first system based on whether or not the first system square sum is within a normal range of first system.

A step of measuring the amount of a target product and the amount of a byproduct after performing a nucleic acid amplification reaction, and a step of determining that a process for removing the byproduct is needed when the abundance ratio of the target product to the byproduct is lower than a prescribed value, and determining the dilution ratio of a reaction liquid after the nucleic acid amplification reaction when the abundance ratio is higher than the prescribed value are included.

Abstract: The present invention provides a simple and highly reliable cell collection system with high throughput and improved in cell collection efficiency. In the present invention, one or more pores are formed in a cell collection plate. One surface of the plate can be directly introduced in e.g., a petri dish, so as to be in contact with a solution containing cells. In this case, means for obtaining an optical image of collected cells from its rear surface is provided to improve reliability and convenience during a cell collection process. Alternatively, the vicinities of the pores in the cell collection plate are only hydrophilized and the other region is made water repellent to improve the efficiency of cell collection.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: There are beforehand prepared a monomer having a reaction residue and a polynucleotide probe set comprising plural kinds of polynucleotide probes having a residue bonded to the reaction residue. The monomer is mixed with each kind of polynucleotide probes comprising any plural probes selected from the polynucleotide probe set. Each kind of the resultant mixtures is added to each of different small holes to make the mixture into gel matrix. Thus, a polynucleotide probe chip is produced. Sample DNA is forcibly migrated in the gels by electrophoresis. Laser light is projected onto the side face of the chip. The fluorescence emitted from the whole surface of the chip is collectively detected with a high-sensitive two-dimensional detector. Thus, the polynucleotide probe chip, holding various kinds of DNA probes, for detecting DNA can be provided. This chip has high hybridization-efficiency and makes high-sensitivity and high-speed DNA detection possible.
