Fig. 3From: Identification of a universal antigen epitope of influenza A virus using peptide microarrayLocations of 14th and 14–4 peptides in simulated HA 3D structure of S strain. The positions of peptide on the hemagglutinin (HA) molecule were analyzed using X-ray crystal structure obtained from the Protein Database. The picture was generated by the SWISS-MODEL system and the PyMOL systemBack to article page
