IMPROVEMENTS IN OR RELATING TO DISPLACEMENT ASSAYS

摘要

Disclosed is a method of detecting the presence of an analyte of interest in the sample, the method comprising the steps of: reversibly immobilising on a first surface a displaceable moiety; exposing the first surface to a sample comprising the analyte of interest, the analyte of interest specifically displacing the displaceable moiety from the first surface; causing the displaceable moiety displaced from the first surface to contact a second surface bearing a capture moiety which specifically binds to the displaceable moiety, so as to capture the displaceable moiety on the second surface, said capture generating a detectable signal; and detecting the signal.
