The four peptides interacting with H7 ‰agellin of Escherichia coli were selected from a phage display library. The library was selected four times, and the interacting phage peptides were competitively eluted with H7 ‰agellin. An enzyme-linked immunosorbent assay (ELISA) showed that these peptides were reactive with the H7 ‰agellin in a dose-dependent manner. Among them, a D1 phage clone showed...

This transaction reports on the on-going attempt to isolate anti-peptide scFv antibodies from an scFv phage-display library capable of detecting the native protein from which the peptide sequence was derived. The display of antibody fragments on the surface of filamentous bacteriophage by fusion to the minor coat protein (plll) and selection of phage with antigen, has provided a powerful method...

This paper presents an analysis of phage-displayed libraries of peptides using Illumina. We describe steps for the preparation of short DNA fragments for deep sequencing and MatLab software for the analysis of the results. Screening of peptide libraries displayed on the surface of bacteriophage (phage display) can be used to discover peptides that bind to any target. The key step in this discov...

Peptide-based molecular probes identified by bacteriophage (phage) display technology expand the peptide repertoire for in vivo diagnosis and therapy of cancer. Numerous peptides that bind cancer-associated antigens have been discovered by panning phage libraries. However, until now only few of the peptides selected by phage display have entered clinical applications. The success of phage deriv...

Phage display technology is undoubtedly a powerful tool for affinity selection of target-specific peptide. Commercially available premade phage libraries allow us to take screening in the easiest way. On the other hand, construction of a custom phage library seems to be inaccessible, because several practical tips are absent in instructions. This paper focuses on what should be born in mind for...

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...

Monoclonal antibody (mAb) 5.5 is directed against the ligand-binding site of the nicotinic acetylcholine receptor. The epitope for this antibody is conformation-dependent, and the antibody does not react with synthetic peptides derived from the receptor sequence. We have identified a ligand peptide that mimics this conformation-dependent epitope from a phage-epitope library composed of filament...

Aiming at identification of novel peptides that can be employed for effective targeting of malignant gliomas, we used a 12-mer peptide phage display library and cultured human malignant glioma cells for phage selection. Several common phage clones emerged after 4 rounds of biopanning against the U87MG glioblastoma cell line. The most abundant phage clone VTW, expressing a sequence of VTWTPQAWFQ...

BACKGROUND/PURPOSE The VPAC1 receptor, a member of the vasoactive intestinal peptide receptors (VIPRs), is overexpressed in the most frequently occurring malignant tumors and plays a major role in the progression and angiogenesis of a number of malignancies. Recently, phage display has become widely used for many applications, including ligand generation for targeted imaging, drug delivery and ...
