Chromatography detection apparatus, detection method, and kit utilizing the same
This invention provides an immunochromatography detection apparatus exhibiting excellent convenience, sensitivity, and specificity, a detection method therefore, a kit using the same, and a method for producing such apparatus and kit, by constructing a solid-phase support, on which the conditions for the reaction wherein an analyte specifically binds to a labeled reagent containing a ligand that specifically binds to the analyte and those for the reaction wherein a capture reagent specifically binds to a complex of the analyte and the labeled reagent in the immunochromatography detection method are continuously optimized, and the pretreated specimens are optimized for such reactions. This chromatography detection apparatus comprises: a sheet-like solid-phase support; a specimen-supply site thereon at which a specimen deduced to contain at least an analyte or a mixture of such specimen and a labeled reagent containing a ligand that specifically binds to the analyte is supplied; and a capture reagent site to which a capture reagent capable of specifically binding to and capturing a complex of the analyte and the labeled reagent has been immobilized, wherein at least one functional site having a particular or multiple functions is provided between the specimen-supply site and the capture reagent site.
