Title:
IMMUNOCHROMATOGRAPHY DEVICE HAVING REDUCED BACKGROUND NOISES, AND METHOD FOR REDUCING BACKGROUND NOISES IN IMMUNOCHROMATOGRAPHTY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/175336
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce background noises in an immunochromatography device to improve the visibility in the immunochromatography device for the purpose of clearly detecting a signal coming from a material to be detected. An immunochromatography device equipped with a membrane that has a detection zone on which an antibody or antigen is immobilized as a capturing substance capable of capturing a substance of interest. In the immunochromatography device, an antigen or antibody labeled with a labeling carrier that is composed of colored particles is used, and a (capturing substance)-(substance of interest)-(labeled antigen or antibody) complex is formed on the capturing substance-immobilized detection zone on the device to detect the substance of interest by the color of the labeling carrier. The device is characterized in that a dye having a color complementary to the color of the labeling carrier is allowed to be contained in a dried state in a constituent member of the device so that the dye can be developed on the device together with a sample when the sample is developed on the device.
