Random peptide libraries displayed on the ribosome are becoming a new tool for the in vitro selection of biologically relevant macromolecules, including epitopes, antagonists, enzymes, and cell-surface receptors. Ribosome display is a cell-free system of coupling individual nascent proteins (phenotypes) to their corresponding mRNA (genotypes) by the formation of stable protein-ribosome-mRNA com...

A random peptide library was expressed on the surface of a mammalian cell by applying retroviral vectors. The random sequence was fused to the CCR5 chemokine receptor, which served as a scaffold to present the library at the cell surface. We used this library to isolate an epitope mimetope in a proof of principle system. This approach can become a tool for rapid creation of peptidic expression ...

The goal of this work is to identify a peptide that can specifically bind bone mineral hydroxyapatite [(Ca5(PO4)3OH)2] from a phage-displayed random peptide library. Instead of using pIII library where random peptides are displayed at the tip of filamentous phage, we used landscape phage libraries, in which random octa-peptides or nona-peptides are displayed on all the N-termini of the pVIII (m...

Phage display peptide libraries are widely used in various protein-protein interaction studies to determine the immunological binding of proteins and epitope mapping of different targets. In the present study, the peptide library is used to identify the Fab binding epitope site of Tetanus Toxoid (TT). The peptides were screened against Fab by biopanning, using a random peptide 12mer phage displ...
