FCS measurements of surface receptor density. By focusing the laser spot of the cell membrane, the number of fluorophores in the probe volume (i.e. the membrane surface) can be estimated. The ratio of bound and unbound receptor ligands is also determined to calculate the surface density of any receptor using any fluorescent probe. Adapted from Reference 16 and 64.
