DISPLACEMENT ASSAY ON A POROUS MEMBRANE

摘要

Displacement assays, under non-equilibrium conditions, are performed by flowing a liquid sample through a membrane (12) having binding elements with binding sites saturated with a labelled form of the analyte. Analyte in the sample displaces, under non-equilibrium conditions, the labelled form of the analyte from the membrane. The displaced labelled form of the analyte may then be detected.
