Abstract

Polypeptide arrays can be synthesized on a substrate by attaching photoremovable groups to the surface of a substrate, exposing selected regions of the substrate to light to activate those regions, attaching an amino acid monomer with a photoremovable group to the activated regions, and repeating the steps of activation and attachment until polypeptides of the desired length and sequences are synthesized. The resulting array can be used to determine which peptides on the array can bind to a receptor.
