WebFluorescence is the light signal we can detect when a fluorophore absorbs energy at a specific wavelength and is excited to emit light at a higher wavelength as it returns to its ground state. During FRET a donor fluorophore becomes excited by a light source and transfers its energy to a nearby acceptor fluorophore.

WebIn this assay, a labeled antigen will compete with unlabeled antigen in the patient sample for a limited number of antibody binding sites. The more unlabeled antigen present in the patient sample, the more unlabeled antigen that will bind to the antibody, resulting in less labeled-antigen binding.
