Abstract: Disclosed are a method of testing a fecal sample, which method suppresses the effect of interfering substances contained in the fecal sample in immunochromatography, to enable accurate and specific measurement of a substance to be detected in the test sample, and an immunochromatographic test piece therefor. The method of testing a fecal sample includes testing the fecal sample by immunochromatography in the presence of a water-soluble polymer. The water-soluble polymer is, for example, a compound containing a polyoxyethylene moiety, or a polyacrylic acid or a salt thereof. The immunochromatographic test piece for testing a fecal sample includes the water-soluble polymer in a sample drop region.

The method of testing a fecal sample includes testing the fecal sample by immunochromatography in the presence of taurodeoxycholic acid or a salt thereof. The immunochromatographic test piece for testing a fecal sample includes taurodeoxycholic acid or a salt thereof in a sample drop region.

Abstract: Disclosed are a norovirus detection method and a device for the detection that enable detection of the major norovirus epidemic strains, GII.2 and GII.4, with high sensitivity. The immunoassay of norovirus utilizes the antigen-antibody reaction between norovirus in a sample and an antibody or an antigen-binding fragment thereof that recognizes the shell domain of the norovirus capsid. The novel immunoassay of norovirus and immunoassay device therefor were provided, which enable detection of GII.2 and GII.4 noroviruses with high sensitivity.

Abstract: Disclosed is an anti-norovirus antibody that reacts with noroviruses of many genotypes and can collectively detect the noroviruses. The anti-norovirus antibody or an antigen-binding fragment thereof undergoes antigen-antibody reaction with the peptides composed of the amino acid sequences of SEQ ID NO: 1 and SEQ ID NO: 2, respectively. The anti-norovirus antibody, which can broadly bind to noroviruses and detect a wide range of human noroviruses with high specificity and sensitivity, and a norovirus immunoassay and a norovirus immunoassay device, both using the anti-norovirus antibody, are provided.

Abstract: A sewing system which includes a detector for detecting an edge of a cloth installed on an installation table, a cloth conveyor for conveying the cloth from the installation table to a sewing machine, and a controller, wherein the cloth conveyor includes a holding member that holds the cloth, and the controller includes a holding position decision portion that determines a holding position of the cloth based on detection data of the detector, and a conveyance control portion that controls the cloth conveyor such that the holding member holds the holding position. In the sewing system according to the above, it is possible to prevent deterioration in productivity of sewn products.

Abstract: A seam inspection device includes an imaging device and a processing device. The imaging device shoots a sewing object supported by a throat plate of a sewing machine and having seams formed therein. And the processing device detects an abnormality of the seam based on an image of the sewing object acquired by the imaging device.
