ABSTRACT:
An assay provides for detecting the presence of an analyte in a sample. Sample is applied to move through three zones. A mobilizeable receptor capable of binding to the analyte is present in the first zone. A trap for unbound receptor, consisting of immobilized ligand, is present in the second zone. Receptor bound to analyte will not bind to the ligand; unbound receptor will bind to the ligand. Mobilization and migration of the receptor can be detected in the third zone, which positively indicates that analyte is present. A device for carrying out the method is also provided.
