摘要
[Problem to be Solved by the Invention] The purpose of the present invention is to provide a competitive immunochromatographic analysis method and immunochromatographic sensor using said analysis method capable of intuitively displaying a molecular concentration of a substance to be measured and facilitating visual judgement of the molecular concentration. [Problem to be Solved by the Invention] Competitive immunochromatographic analysis method according to the present invention is characterized in that the method comprisesa step for supplying a mixed solution, in which a test solution containing a substance to be measured A and a labeled antibody B are mixed, to one or more judgement parts wherein said judgement parts are formed by immobilizing a text antibody C which specifically reacts with the labeled antibody B specifically reacting with the substance to be measured A on a membrane carrier in the form of character(s) or figure(s) and immobilizing a mask antigen D composed of the same antigen as the substance to be measured A on the membrane carrier so as to surround said text antibody C,a step for competitively binding the labeled antibody B to the substance to be measured A, the mask antigen D and the text antibody C on the judgement parts,a step for judging the concentration of the substance to be measured A based on the signal from the labeled antibody B bound to the text antibody C and the mask antigen D.展开▼
