Abstract: A cartridge to be installed in a detection device for detecting light generated from a measurement sample containing a test substance is provided. The cartridge includes: a plurality of detection chambers fluidly isolated from each other and each receiving a measurement sample; and a transmission suppression unit provided between one detection chamber and another detection chamber of the plurality of detection chambers, and configured to suppress transmission of light generated from a measurement sample in the one detection chamber to the another detection chamber.

Abstract: A method according to one or more aspects may be a method of measuring a detection material contained in a sample by using a cartridge including: chambers each capable of housing at least one of the detection material and a reagent; and a path through which the detection material is transferred between the chambers. The method may include: moving at least one of the chambers and the path to a measurement position and an image capturing range by rotating the cartridge about a rotational shaft; measuring the detection material in the measurement position; and capturing an image of a monitoring target comprising at least one of the chambers and the path in the image capturing range.

Abstract: A detection method for detecting a detection target substance is provided. The method includes a first application step of applying a magnetic field a liquid suspension to link a plurality of magnetic particles in a row from an interior surface of a liquid receiving member that receives the liquid suspension of magnetic particles to which a detection target substance is bound, a second application step of bringing the linked magnetic particles near the interior surface while the magnetic field is applied to the liquid suspension, and a detection step of detecting the detection target substance bound to the magnetic particles brought near the interior surface by the second application step, wherein the direction of the magnetic field applied to the liquid suspension is altered so the linked magnetic particles approach the interior surface in the second application step.

Abstract: A urine specimen analysis device includes a specimen drawing portion, a sample preparing portion, a measurement portion, and an information processing portion. The specimen drawing portion draws a first aliquot and a second aliquot from a urine specimen. The sample preparing portion prepares a first measurement sample by mixing the first aliquot and a first staining dye that stains red blood cells, and a second measurement sample by mixing the second aliquot and a second staining dye that stains nucleic acids. The measurement portion measures fluorescence emitted from the first measurement sample prepared by the sample preparing portion, and fluorescence emitted from the second measurement sample prepared by the sample preparing portion.

Abstract: A method of measuring an enzyme activity, which comprises the steps of: (1) introducing a sample containing an enzyme to be measured into a column packed with a packing material comprising a water-insoluble support and an antibody which is immobilized onto the support and which recognizes the enzyme to be measured, to thereby capture the enzyme with the antibody; (2) introducing a substrate for the enzyme into the column to react the enzyme captured by the antibody with the substrate; and (3) detecting a product obtained by the reaction. The above method allows the rapid measurement of an enzyme activity with good reaction efficiency.
