Abstract

Phage display is a versatile and effective platform for the identification and engineering of biologic-based therapeutics. Using standard molecular biology laboratory techniques, one can create a highly diverse and functional antibody phage-displayed library, and rapidly identify antibody fragments that bind to a target of interest with exquisite specificity and high affinity. Here, we discuss key aspects for the development of an antibody discovery strategy to harness the power of phage display technology to obtain molecules that can successfully be developed into therapeutics, including target validation, antibody design goals, and considerations for preparing and executing phage panning campaigns. Careful design and implementation of discovery campaigns-regardless of the target-provides the best chance of identifying desirable antibody fragments for further therapeutic development, so these principles can be applied to any new discovery project.
