Abstract: Ribosome display is a cell-free system for the selection of proteins and peptides from large libraries. It uses the principle of coupling the translated proteins(phenotypes)and their corresponding mRNA(genotypes)to ribosome and the stable protein-ribosome-mRNA complexes are formed. Then,the functional proteins and the corresponding encoding mRNAs are obtained by the simultaneous affinity separation of ligands,and they are converted and amplified as DNA for further expressions of related proteins,as well as selection of antibody and protein libraries,in vitro modification of proteins. It may display very large libraries while it is not limited by bacterial transformation. It is also suitable for screening the toxic,proteolytically sensitive,and unstable proteins,and allows the incorporation of modifying amino acids at defined loci. In this paper,research progress on ribosome display systems and their applications in the selection and evolution of proteins are reviewed.

Key words: ribosome display, antibody, selection, protein evolution
