SHEET, KIT, AND METHOD FOR DETECTING ANTIGEN OR ANTIBODY

摘要

PROBLEM TO BE SOLVED: To provide a sheet, kit, and method for detecting antigen or antibody by which an antigen or antibody contained in a biological solution can be detected with high sensitivity through simple operation. SOLUTION: A sheet for detecting antigen or antibody is constituted by immobilizing avidin or streptavidin to a fiber aggregate carrying particles of a calcium phosphate compound having an average particle diameter of 0.01-200μm and a Ca/P ratio of 1.0-2.0. By bonding an antibody or antigen contained in a sample solution to the immobilized avidin or streptoavidin by bringing the sheet into contact with the sample solution after bonding a biotinized antigen or antibody to the avidin or streptoavidin and bringing the sheet into contact with the solution of a labeled compound which is specifically bonded to the antibody or antigen in the sample solution, a labeled antigen- antibody complex is detected.
