Like the two-hybrid system, phage display is used for the high-throughput screening of protein interactions.In the case of M13 filamentous phage display, the DNA encoding the protein or peptide of interest is ligated into the pIII or pVIII gene, encoding either the minor or major coat protein, respectively.
In immunology, affinity maturation is the process by which T FH cell-activated B cells produce antibodies with increased affinity for antigen during the course of an immune response. With repeated exposures to the same antigen, a host will produce antibodies of successively greater affinities .

John McCafferty is a British scientist, one of the founders of Cambridge Antibody Technology alongside Sir Gregory Winter and David Chiswell. He is well known as one of the inventors of scFv antibody fragment phage display, [1] a technology that revolutionised the monoclonal antibody drug discovery.
The first step is to have phage display libraries prepared. This involves inserting foreign desired gene segments into a region of the bacteriophage genome, so that the peptide product will be displayed on the surface of the bacteriophage virion. The most often used are genes pIII or pVIII of bacteriophage M13. [5]
Bacterial display (or bacteria display or bacterial surface display) is a protein engineering technique used for in vitro protein evolution. Libraries of polypeptides displayed on the surface of bacteria can be screened using flow cytometry or iterative selection procedures (biopanning). This protein engineering technique allows us to link the ...
A single-domain antibody is a peptide chain of about 110 amino acids long, comprising one variable domain (V H) of a heavy-chain antibody, or of a common IgG.These peptides have similar affinity to antigens as whole antibodies, but are more heat-resistant and stable towards detergents and high concentrations of urea.
Internalizing RGD (iRGD) peptides are a class of 9-amino acid cyclic peptides containing an RGD sequence, which undergo internalization as discussed below. The prototypic iRGD peptide, shown in the image on the right (sequence: CRGDKGPDC; CAS 1392278-76-0), was originally identified in an in vivo screening of phage display libraries in tumor-bearing mice.
