Figure 1From: Changed epitopes drive the antigenic drift for influenza A (H3N2) virusesOverview of our method for the antigenic drift. (A) The overview of our method. (B) The structural locations of selected 64 critical amino acid positions on five epitopes (Epitope A in red; B in purple; C in orange; D in cyan; E in green). The sialic acid is in green. All structures are presented by using PyMOL.Back to article page
