The spread from the recently emerged highly pathogenic H5N1 avian influenza virus has raised concern. of clade 2.2.2. Epitope-mapping analysis revealed that MAb 9F4 binds a previously uncharacterized epitope below the globular head of the HA1 subunit. Consistently this epitope is usually well conserved among the different clades of H5N1 viruses. MAb 9F4 does not… Continue reading The spread from the recently emerged highly pathogenic H5N1 avian influenza
