Abstract:
A system for determining affinity of a receptor to a ligand, comprising:(a) a substrate that comprises a plurality of ligands at known locations; (b) an optical arrangement that directs light to a surface of the substrate; (c) a support upon which the substrate can be placed, wherein when the substrate is placed on the support and operatively aligned with respect to the optical arrangement, the optical arrangement simultaneously illuminates an area of the substrate, wherein the illuminated area is a fraction of each of a plurality of the known locations, which plurality of known locations is a subset of the known locations; and (d) a detector that detects the amount of light from the illuminated area as a function of position.
