Abstract: A nucleic acid analysis device is provided that is capable of quickly detecting device abnormalities, and the like. This device is provided with a temperature control block (1) for holding a tube (10) that includes a sample, a photometer (6), and a device diagnosis unit. The photometer (6) is provided with an LED (11) for irradiating light toward the temperature control block (1) in a state in which the tube (10) is held and a fluorescence detector (20) for receiving light emitted by the sample in response to the irradiation of light from the LED (11). The device diagnosis unit causes the LED (11) to irradiate light toward the temperature control block (1) in a state in which the tube (10) is not held, causes the fluorescence detector (20) to detect the resulting scattered light, and diagnoses the photometer (6) on the basis of the intensity of the scattered light.

Abstract: The nucleic acid amplification device is configured to amplify the nucleic acid in the reaction solution obtained by mixing a specimen and a reagent and includes a plurality of temperature regulation block configured to hold at least a reaction container provided on a holder base. The order and timings in which the reaction containers are continuously installed on the temperature regulation blocks and in which the temperature regulations of the temperature regulation blocks are started are controlled to minimize the temperature gradient in the holder base.

Abstract: The present invention has an object to provide an automatic analyzer using a disc, which treats samples with different pretreatment times or samples with different measurement times requested at random with high throughput. The present invention relates to performing adjustment rotation, rotation returning to origin, and measurement rotation in specimen analysis using a disc having a plurality of sample positions on a circumference. The adjustment rotation is an operation for placing a desired sample position in a particular position for introducing a sample into the disc or discarding the sample. The rotation returning to origin is an operation for placing an origin of the disc in a particular position. The measurement rotation is an operation for rotating the disc at a predetermined speed for measuring a plurality of samples held by the disc.

Abstract: It is an object of the present invention to prevent condensation occurring when reaction solutions in sealed vessels are heated in a nucleic acid analyzer for performing sequential processing in which individual reaction vessels are sequentially fed to a nucleic acid amplification unit in a given cycle. This invention relates to a nucleic acid analyzer including a vessel mounting rack capable of holding the plurality of reaction vessels, wherein the reaction vessel mounted on the vessel mounting rack is heated by an adjacent noncontact heat source and air circulation from the heat source to a reaction vessel upper portion, and a temperature of the reaction vessel upper portion is kept higher than a temperature of a reaction vessel lower portion. With this invention, condensation possibly occurring on the inner wall of the sealed vessel upper portion due to heating during nucleic acid amplification can be prevented, and more accurate nucleic acid analysis is enabled.

Abstract: Based on a partial sequence of a target gene having an unidentified sequence, a partial sequence corresponding thereto is extracted from a genome sequence by homology search on a database. Exon regions are predicted using plural programs, respectively, and common sequences among the predicted exon regions are extracted. A set of primers is designed based on a combination of a 5′ end sequence and a 3′ end sequence selected from the plurality of common sequences. Amplification using the selected combination of 5′ end and 3′ end sequences as a set of primers results in an amplified gene that may be cloned. A display system for preparing primer sequences and utilizing the prepared primer sequences.
