Abstract
Analytes can be detected from among closely related substances by reacting the analyte in a test sample with a labeled binding agent which specifically binds to the analyte to form a complex. The labeled binding agent is supplied in excess, and the complex is identified through a time window relative to the detection of the excess unbound agent. The complex and labeled binding agent are isolated on a separation media and identified by the differential rate of migration.
