Abstract

A method is disclosed which rapidly detect allergens with good accuracy by efficiently extracting the allergens from a test sample such as food containing various allergens and eliminating non-specific reactions accompanying the disintegration of colloidal gold conjugated to antibodies by not using a reducing agent. The method uses a developing solution containing at least 10% by weight of FBS in an immunochromatography method which comprises using a colloidal gold-labeled antibody in which a colloidal gold is bound to a monoclonal antibody against denatured and native allergen, a development support wherein a monoclonal antibody against denatured and native allergen recognizing an epitope different from that recognized by the colloidal gold-labeled antibody is fixed, measurement samples of the allergens extracted from the test sample with an anionic surfactant such as SDS and a thiosulfate or an anionic surfactant such as SDS and a non-ionic surfactant such as Tween 20, and the developing solution; developing the developing solution on the development support; and then detecting the allergens based on the presence of the deposition of the colloidal gold.
