The display of cDNA libraries via phage display is an attractive alternative to the yeast-2-hybrid method for the discovery of interacting proteins and peptides due to its high throughput capability. [ 34 ] pVI has been used preferentially to pVIII and pIII for the expression of cDNA libraries because one can add the protein of interest to the ...
Creative Biolabs, Inc. is a life-science company which produces and supplies biotech products and services for early drug discovery and development, including various phage display libraries [1] such as pre-made libraries, [2] phage display services, [3] [4] antibody sequencing, [5] and antibody humanization.

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.
Biopanning is an affinity selection technique which selects for peptides that bind to a given target. [1] All peptide sequences obtained from biopanning using combinatorial peptide libraries have been stored in a special freely available database named BDB. [2] [3] This technique is often used for the selection of antibodies too.
Phage display is a different use of phages involving a library of phages with a variable peptide linked to a surface protein. Each phage genome encodes the variant of the protein displayed on its surface (hence the name), providing a link between the peptide variant and its encoding gene.
A mimotope is often a peptide, and mimics the structure of an epitope. Because of this property it causes an antibody response similar to the one elicited by the epitope. An antibody for a given epitope antigen will recognize a mimotope which mimics that epitope. Mimotopes are commonly obtained from phage display libraries through biopanning.
Comparison of natural and synthetic selection processes for peptide generation. In biotechnology, combinatorial biology is the creation of a large number of compounds (usually proteins or peptides) through technologies such as phage display. Similar to combinatorial chemistry, compounds are produced by biosynthesis rather than organic chemistry.
The most common peptide aptamer selection system is the yeast two-hybrid system. Peptide aptamers can also be selected from combinatorial peptide libraries constructed by phage display and other surface display technologies such as mRNA display, ribosome display, bacterial display and yeast display.
