Abstract: A degree of polarization of second reference samples produced by adding an antibody, a tracer, and a target substance having mutually different concentrations to a first reference sample not including the target substance is corrected with a degree of polarization of the first reference sample to generate a first calibration curve. A degree of polarization of a second sample to be measured produced by adding the antibody and the tracer to a first sample to be measured in amounts equal to those added to the second reference samples is corrected with a degree of polarization of the first sample to be measured to obtain the concentration of the target substance in the first calibration curve.

Abstract: A substance separating device includes a reaction vessel provided with an interior that is partitioned into a first chamber and a second chamber by a dialysis membrane, a solution being stored in the reaction vessel. A specimen is stored in the first chamber, and dye-modified molecule that has a binding ability for specifically binding to a substance to be measured having a molecular weight greater than a molecular weight cut-off the dialysis membrane is stored in at least one of the first chamber and the second chamber. The dye-modified molecule has a molecular weight that is less than the molecular weight cut-off of the dialysis membrane.

Abstract: A concentration estimation kit includes a derivatization reagent that derivatizes at least a portion of an antigen included in a mixed specimen, and that is for obtaining a plurality of samples having different derivatization rates, the derivatization rate being a ratio of a derivatized antigen relative to the antigen included in the specimen; an antibody that binds to the antigen; and the antigen modified with a dye.

Abstract: Provided is a support for fluorescence polarization immunoassay of which reaction parts are loaded with an antibody and a fluorescent labeling substance. The plurality of reaction parts may be loaded with different concentrations of an antibody and a fluorescent labeling substance. Further, antibodies having different binding affinities for a target substance may be loaded. With such a support, fluorescence polarizations can be measured simply by adding a sample solution containing a target substance to the reaction parts, and a wide measurement range of the concentration the target substance can be secured.

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.

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.
