International ClassG01N 33/53AbstractAn analytical strip and a detecting method using the analytical strip are provided. The analytical strip includes a substrate having a channel thereon. The channel has a first region, a second region and a third region, which are connected sequentially. A first antibody is localized in the first region. A saccharide and a peroxidase are localized in the first or second region. A second antibody for recognizing a different epitope of an identical antigen with the first antibody is immobilized in the second region. An optical substrate and a substrate reagent including a saccharide oxidase are localized in the third region.Other References
