  • Method for analyzing samples and device for analyzing samples
    Patent number: 11169071
    Abstract: In a method for analyzing samples involving the use of a device for analyzing samples, the device for analyzing samples includes at least a movement part through which a sample moves, and a measurement unit that is formed in a middle of the movement part and that measures a value of an ion current when the sample passes through the movement part. The analysis method includes at least a measurement step for measuring the value of the ion current when the sample passes through the movement part, and a determination step for determining a change over time in a quantity of ions from the value of the ion current measured in the measurement step. The quantity of ions includes a quantity of ions that have leaked from the sample during movement of the sample through the movement part.

  • FLUORESCENCE POLARIZATION IMMUNOASSAY AND FLUORESCENT LABELING SUBSTANCE
    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.
