Abstract:
1. An immunochromatographic device, which contains the following (a) and (b): (a) a first device part holding a first insoluble carrier used for developing a complex formed with an analyte and a labeling substance comprising a metal labeled with a first binding substance that can bind to the analyte and used for capturing the analyte and the labeling substance, wherein the first insoluble carrier includes a sample-adding pad, a labeling substance-retaining pad containing the labeling substance therein or thereon, a chromatographic carrier containing at a reaction portion a second binding substance that can bind to the analyte, and an absorbent pad in this order from the upstream to the downstream of the development direction; and (b) a second device part holding a second insoluble carrier used for developing a liquid and a third insoluble carrier used for absorbing a liquid, wherein the first device part (a) and the second device part (b) are contained in the immunochromatographic device in a state where the first insoluble carrier is not in contact with the second insoluble carrier and the third insoluble carrier, and the first device part has a liquid storage pot.
