BACKGROUND Amino acid sequence diversity is introduced into a phage-displayed peptide library by randomizing library oligonucleotide DNA. We recently evaluated the diversity of peptide libraries displayed on T7 lytic phage and M13 filamentous phage and showed that T7 phage can display a more diverse amino acid sequence repertoire due to differing processes of viral morphogenesis. METHODS In t...

Phage display technologies are powerful tools for selecting binding ligands against purified molecular targets, live cells, and organ vasculature. However, the selection of natural ligands using phage display has been limited because of significant problems associated with the display of complex cDNA repertoires. Here we describe the use of cDNA fragmentation and open reading frame (ORF) select...

There has been a resurgence of interest in immunotherapies for cancer, particularly concerning the isolation of novel antigens which distinguish cancer cells from normal cells. Recently i t was demonstrated that the humoral immune response can be used to isolate novel tumour antigens. This involved the probing of a tumour specific cDNA expression library in h phage with autologous patient serum...

Phage display is a powerful technique for profiling specificities of peptide binding domains. The method is suited for the identification of high-affinity ligands with inhibitor potential when using highly diverse combinatorial peptide phage libraries. Such experiments further provide consensus motifs for genome-wide scanning of ligands of potential biological relevance. A complementary but con...

The aim of this study was to identify potential ligands and develop a novel diagnostic test to pathogenic bovine rotavirus (BRV) using phage display technology. The viruses were used as an immobilized target followed by incubation with a 12-mer phage display random peptide library. After five rounds of biopanning, phages had a specific binding activity to BRV were isolated. DNA sequencing indic...
