Abstract: Disclosed herein are methods for immobilizing a peptide or protein on a solid support. The method generally includes the following steps: (a) providing one or more templates attached to a solid support, wherein the one or more templates include (i) an RNA encoding a peptide and (ii) a peptide acceptor-linker linked to the RNA; and (b) subjecting the one or more templates to conditions that support translation and attachment of said peptide to said peptide acceptor, thereby synthesizing the one or more peptides on the solid support. Also disclosed herein are solid supports having at least one RNA-protein fusion component immobilized thereon, methods for generating protein arrays, and methods for screening molecules using these arrays.
