Phage Display Service


Phage display is a powerful in vitro screening technology and one of the most effective molecular diversity techniques. The technology is based on the direct linkage between the phage phenotype and its encapsulated genotype so that the molecular library is displayed on the surface of the phage. This technology can screen libraries with more than one billion members in just a few days, providing an effective alternative to traditional epitope mapping, molecular interaction, and receptor/ligand identification, etc.

Phage display is widely used to study protein-ligand interactions and receptor binding sites, as well as to improve or modify the affinity of proteins for their binding partners. Phages have been used in immunotherapy, which has greatly promoted the development of new tools for the treatment of autoimmune and cancer diseases.
