Reported monoclonal antibodies against B cell epitopes of HA2 polypeptide derived from influenza A virus strains.

aPreviously reported monoclonal antibodies against each highly conserved B cell epitope in the HA2 polypeptide.bWe synthesized previously reported B cell epitope sequences from the HA2 polypeptide to prepare a complex containing each epitope and Lipoplex(O) in this study.cAbbreviations of each B cell epitope used in this study.
