  • Publication number: 20210341488
    Abstract: A fluorescence polarization immunoassay that uses a fluorescent labeling substance in which a single domain antibody is labeled with a fluorescent dye. A fluorescent labeling substance obtained by labeling a single domain antibody, such as a VHH antibody or a vNAR antibody, having a binding ability to a target substance with a fluorescent dye is used. The fluorescence polarization immunoassay includes a binding step for binding the fluorescent labeling substance to a target substance; and a measuring step for measuring a change in the fluorescence polarization of the fluorescent labeling substance to which the target substance is bound.

  • Publication number: 20210310912
    Abstract: A sample solution preparation method, a measurement cell, a measurement kit, and a sample solution preparation device for measuring a target compound contained in food by an immunity analysis method using fluorescence. The present disclosure features including a dialysis step for bringing a target compound-containing solution that includes the target compound into contact with a dialysis fluid through a dialysis membrane to transfer the target compound to the dialysis fluid, in which the molecular weight cut-off of the dialysis membrane is within a range of 2×102 to 2×105, and the volume of the dialysis fluid is relatively smaller than the volume of the target compound-containing solution.

  • Patent number: 10824002
    Abstract: A display apparatus includes a display device configured to display an original image at an original image display position, a second array of a lens array or a pinhole array, and a first array of a lens array or a pinhole array disposed distant from the display device and the second array between the display device and the second array. The first array is configured to form a plurality of elemental images generated from the original image at positions between the first array and the second array. The pitch of the plurality of elemental images is different from lens pitch or pinhole pitch of the second array. The second array is configured to integrate the plurality of elemental images to generate a single reproduced image of the original image.
