Abstract:
An analyte, such as an antigen, is initially contacted with a receptor (antibody) bound to a solid support, in the absence of tracer, followed by removal of unbound analyte and contacting with tracer. By separately contacting the receptor with analyte and tracer, sensitivity is increased.
