Identification of a Conserved B-cell Epitope on Reticuloendotheliosis Virus Envelope Protein by Screening a Phage-displayed Random Peptide Library

BACKGROUND The gp90 protein of avian reticuloendotheliosis-associated virus (REV-A) is an important envelope glycoprotein, which is responsible for inducing protective antibody immune responses in animals. B-cell epitopes on the gp90 protein of REV have not been well studied and reported. METHODS AND RESULTS This study describes the identification of a linear B-cell epitope on the gp90 protei...

Identification of a Conserved Linear B-Cell Epitope of Streptococcus dysgalactiae GapC Protein by Screening Phage-Displayed Random Peptide Library

The GapC of Streptococcus dysgalactiae (S. dysgalactiae) is a highly conserved surface protein that can induce protective humoral immune response in animals. However, B-cell epitopes on the S. dysgalactiae GapC have not been well identified. In this study, a monoclonal antibody (mAb5B7) against the GapC1-150 protein was prepared. After passive transfer, mAb5B7 could partially protect mice again...

Antibody and Antigen Binding Peptides Using a Phage Displayed Random Peptide Library

Development of antiangiogenin peptide using a phage-displayed peptide library.

Angiogenesis is essential for tumor growth and metastasis. Here, we have developed a peptide antagonist of human angiogenin, which is a potent and tumor-associated angiogenic factor. ANI-E peptide was derived from the phage clone, which binds to angiogenin via the disulfide-constrained octapeptide epitope that is displayed on its surface, and is displaced by actin. Disulfide-constrained ANI-E p...
