    Abstract

    Analysis of the anti-haemagglutinin serum antibody proteome from six H1N1pdm09 influenza A vaccinated subjects demonstrated restricted IgG1 heavy chain species encoded by IGHV5-51 and IGHV3-7 gene families in 2 subjects and either IGHV5-51 or IGHV3-7 in 4 individuals. All subjects exhibited a dominant IGKV3-20 light chain, however 5 subjects also exhibited IGKV3-11 and IGKV4-1 families. Sequences were closely aligned with the matched germline sequence, with few shared mutations. This study illustrates the feasibility of using a proteomic approach to determine the expressed V region signatures of serum antibodies induced by vaccination.
