Phage Display Service

Phage display technology is a new technology in which exogenous peptide or protein genes and phage specific protein genes are fused and expressed on its surface. This technology realizes the unification of phenotype and genotype. With the further development of phage display technology, its superiority is recognized by more and more laboratories, which makes the scope of use of this technology continue to expand, and also enables continuous improvement and development of this technology.

Technical principle

After the exogenous DNA fragment encoding the polypeptide is fused with the gene encoding the phage surface protein, it is displayed on the surface of the phage in the form of a fusion protein. The displayed polypeptide or protein can maintain relative spatial structure and biological activity and be displayed on the surface of the phage. A group of phages introduced with various foreign genes constitutes a phage display library displaying various foreign peptides. When a protein is used to screen a phage display library, it will be selectively combined with a foreign peptide that interacts with it to isolate a specific phage in the display library and study the phage contained the biological function of foreign genes.

Overall Solutions

✓ CD BioSciences provides a phage display platform for in vitro discovery and engineering of effective antibody candidates for therapeutic or diagnostic purposes.

✓ CD BioSciences uses custom-made or licensed state-of-the-art technology libraries to routinely select high-affinity functional antibodies against a wide range of conventional or challenging targets (such as GPCRs).

✓ CD BioSciences can provide a variety of antibody scaffolds upon request.

✓ CD BioSciences' unparalleled in vitro antibody discovery function can be bundled with unique lead optimization, characterization and downstream large-scale GMP production, so it can provide the full range of early to late antibody drug generation services.

Our Advantages

✓ The advantage of phage display technology is that it provides a direct physical connection between the protein and its genetic information, so that people can effectively screen the clones with the required functions and then amplify them. CD BioSciences specializes in phage display service and we are committed to contributing to more customers and we can provide all services related to phage display service in a flexible and comprehensive manner.

✓ CD BioSciences has in-depth cooperation with many pharmaceutical companies and research institutes, and has extensive experience in providing them with high-quality products and services.
