Abstract
Display technology refers to a collection of methods for creating libraries of modularly coded biomolecules that can be screened for desired properties. It has become a routine tool for enriching molecular diversity and producing novel types of proteins. The combination of an ever-increasing variety of libraries of modularly coded protein complexxes with the development of innovative approaches to select a wide array of desired properties has facilitated large-scale analyses of protein–protein/protein–substrate interactions, rapid isolation of antibodies (or antibody mimetics) without immunization, and function-based protein analysis. Several practical and theoretical challenges remain to be addressed before display technology can be readily applied to proteomic studies.
