Epitope mapping of hepatitis C virus non-structure protein 5 from a 7 peptide phage library by using immobilized specific monoclonal antibody / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To screen HCV NS5 mimotopes by using monoclonal antibody and phage peptide library.</p><p><b>METHODS</b>By using HCV NS5 monoclonal antibody as selective molecule, a 7 peptide phage library was biopanned and positive clones were selected by ELISA, competition assay and DNA sequencing.</p><p><b>RESULTS</b>Twelve positive clones were chosen for DNA sequencing. From the experiment and sequencing comparison results, one epitope was confirmed as the mimotope of HCV NS5.</p><p><b>CONCLUSIONS</b>HCV mimotope is obtained by phage peptide library screening. The result provides a new approach for HCV therapy and vaccine development.</p>
