  • Publication number: 20220011306
    Abstract: A problem to be solved is to provide an immunochromatographic test strip in which a specimen sufficiently and quickly permeates into a sample application region within a test time so that variations in detection values of a test line can be prevented. Particularly, a problem to be solved is to provide an immunochromatographic test strip causing less variations in detection values even when the specimen is whole blood. The problems are solved by providing an immunochromatographic test strip including at least a sample application region, a development region, and a detection region, wherein the sample application region contains polyethylene glycol having a molecular weight of 15,000 to 700,000.

  • Publication number: 20190094215
    Abstract: The present invention addresses the problem of making it possible, in a simple immunoassay, to prevent false-positive reactions and reduce measurement value errors so as to accurately detect fFN by suppressing a cross-reaction with plasma FN that is an antigenic component similar to fFN to reduce the detection of plasma FN. When an anti-fFN antibody reacts with fFN in the presence of a specific surfactant according to the present invention, it is possible to accurately detect fFN through the suppression of the cross-reaction between the antibody and FN, even when other FNs such as plasma FN are also present. The specific surfactant is represented by general formula (1): R—O—(CH2CH2O)mH??(1) In the formula, m is 4-30, and R represents an alkyl group.

  • Patent number: 9811715
    Abstract: An image generator configured to generate a face detecting image used in face detection processing of detecting a face from an image, has a representative luminance calculator that calculates a representative luminance value representing a luminance value of each pixel of a photographed image obtained by photographing; and a gamma converter that generates the face detecting image by performing gamma conversion processing on the photographed image. The luminance value of each pixel of the image is converted using a predetermined gamma value. The gamma converter performs the gamma conversion processing using a first gamma value when the representative luminance value calculated by the representative luminance calculator is greater than or equal to a predetermined threshold.
