Chromatographic test strip for determining ligands or receptors |
摘要 |
A test strip for analysis of analytes such as antigens, antibodies or polynucleotides employs a chromatographic medium and a solvent capable of transporting reagents and/or sample. Reagents are selected and disposed on the medium such that a labeled (first) reagent arrives at the detection (third) zone only after analyte is immobilized there and non-reactive sample componets have been transported beyond the detection zone. This sequential arrival is accomplished by the relative mobility of the reagent or sample; or by the site relationship of the zones. Preferably, the site relationship of the sample (second) zone and the label (first) zone is such that a plurality of pathways guide the sample and labeled reagent and any subsequent reagents to the detection zone in the recited order. Single and multiple pathway devices are disclosed.
