Introduction to Phage Display
Phage display is a groundbreaking biotechnology that enables the study of protein-protein, protein-peptide, and protein-DNA interactions. This technique involves the presentation of foreign peptides or proteins on the surface of bacteriophages (viruses that infect bacteria), allowing researchers to screen and identify high-affinity binding molecules efficiently.
Since its development by George P. Smith in 1985, phage display has become a cornerstone in drug discovery, antibody engineering, epitope mapping, and vaccine development.
How Phage Display Works
The phage display process involves several key steps:
Library Construction – A diverse library of DNA sequences encoding peptides or antibody fragments is inserted into phage genes, resulting in the display of these variants on the phage surface.
Panning (Selection) – The phage library is exposed to a target molecule (e.g., an antigen, receptor, or enzyme). Phages displaying high-affinity binders are retained, while non-binders are washed away.
Amplification – The selected phages are amplified in bacteria to enrich the pool of high-affinity clones.
Screening & Characterization – Individual clones are isolated, and their binding properties are analyzed using techniques like ELISA, sequencing, or surface plasmon resonance (SPR).
Applications of Phage Display
Phage display has revolutionized biomedical research and therapeutic development, with applications including:
Antibody Discovery – Generation of monoclonal antibodies (mAbs) for diagnostics and therapeutics.
Peptide Drug Development – Identification of bioactive peptides for targeting diseases.
Epitope Mapping – Determining antibody-binding sites on antigens.
Protein Engineering – Improving protein stability, affinity, and function.
Biomarker Discovery – Finding novel disease-associated molecules.
