Location of confirmed glycosylation sites in relation to the most relevant antigenic sites on A/New Caledonia/20/1999 H1. (A) View of the globular head of H1 from the top. (B) View of H1 from the side to highlight the distribution of glycosites along the stalk region and the side of the globular head. Monomeric H2 (PDB entry, 2WR3) was used as a template to generate the homology model of A/New Caledonia/20/1999 H1.
