Abstract

ABSTRACT: A peptide enzyme linked immunosorbent assay (ELISA) based on an epitope in the haemagglutinin (HA) of avian influenza virus H5N1, amino acid positions 274–288 (HA274–288) was evaluated for detection of H5N1-specific antibodies. An optimized ELISA based on the tetrameric form of the HA274–288 epitope designated MP15 gave low background with non-immune chicken sera and detected vaccinated and infected birds. The HA274–288 epitope was highly conserved in Indonesian H5N1 strains and antibody responses were detected in the majority of the vaccinated chickens regardless of the H5N1 strain used for vaccination. The HA274–288 epitope was also conserved in the majority of H5N1 strains from ..
