The Screen of Inhibitors of Grass Carp Hemorrhage Virusfrom a Phage Displayed Random Peptide Library

Screening inhibitors of GCHV 873 (Grass Carp Hemorrhage Virus)to inhibit its replication in CIK cells in vitro ,the biotinylated intact virion of GCHV was used to react on a random sequenced peptide library of 9 amino acids fused on protein Ⅲ of filamentous phage fUSE5 .After 3 rounds of affinity selection,immuno screening and ELISA,16 positive clones were selected using CsCl gradient purified virus particles, 6 of them inhibited the replication of GCHV in CIK cells in vitro and decreased the TCID 50 of GCHV from 10 -10 to 10 -5 .These findings open possibility of identifying virus proteins or epitopes as targets for antiviral agents.
