phage display

laboratory technique

Quick Summary

Phage display is a laboratory technique developed by George P. Smith that uses bacteriophages to study protein interactions. Bacteriophages are viruses that infect bacteria. In phage display, foreign DNA fragments are fused into phage gene III, causing the resulting proteins to be displayed on the surface of the phage virion. This allows researchers to use antibodies to select for specific fusion phages, effectively amplifying foreign gene sequences for further study. This technique has been crucial in developing antibody-based therapies, such as Adalimumab (Humira), used to treat rheumatoid arthritis. For their work on phage display, Smith and Greg Winter were awarded the Nobel Prize in Chemistry in 2018.12
