Yeast surface display for antibody isolation: library construction, library screening, and affinity maturation.

Antibodies play key roles as reagents, diagnostics, and therapeutics in numerous biological and biomedical research settings. Although many antibodies are commercially available, oftentimes, specific applications require the development of antibodies with customized properties. Yeast surface display is a robust, versatile, and quantitative method for generating these antibodies and is accessible to single-investigator laboratories. This protocol details the key aspects of yeast surface display library construction and screening.
