An immunochromatographic test strip for extracting and measuring a sugar chain antigen capable of controlling the development of a sample by impregnating a hydrophobic material with nitrite or a solid acidic reagent

摘要

PROBLEM TO BE SOLVED: To provide an immunochromatographic test strip for controlling the development of a sample on an immunochromatographic test strip and appropriately controlling the treatment with an acidic reagent, a nitrite and a neutralizing reagent, and an immunochromatographic method using the test strip. The purpose is to provide. A sample pad to which a specimen mixed with a nitrite or an acidic solution is added, a labeled region containing a labeled antibody labeled with an antibody against a sugar chain antigen, and a detection region immobilized with an antibody against the sugar chain antigen are included. An immunochromatographic test strip for measuring a sugar chain antigen by forming a complex of antibody-sugar chain antigen-labeled antibody in the detection area, which has an area impregnated with a neutralizing reagent upstream of the labeled body area. Further, upstream of the region impregnated with the neutralizing reagent, there is a region impregnated with a solid acidic reagent when using a sample mixed with nitrite, and when the sample mixed with an acidic solution is used, impregnated with nitrite. An immunochromatographic test strip for extracting and measuring a sugar chain antigen in a specimen, which has a region made to have a characteristic that a hydrophobic material is used in a region impregnated with nitrite or a solid acidic reagent. , Immunochromatographic test piece.
