title: In vitro selection as a powerful tool for the applied evolution of proteins and peptides.
abstract: New in vitro methods for the applied evolution of protein structure and function complement conventional cellular and phage-based methods. Strategies employing the direct physical linkage of genotype and phenotype, and the compartmental association of gene and product to select desired properties are discussed, and recent useful applications are described. Engineering of antibodies and other proteins, selection from cDNA libraries, and the creation of functional protein domains from completely random starting sequences illustrate the value of the in vitro approaches. Also discussed is an emerging new direction for in vitro display technology: the self-assembly of protein arrays.
