Fig. 5From: Identification of a universal antigen epitope of influenza A virus using peptide microarrayVariation in 14–4 peptide in influenza A viruses was analyzed using WebLogo3. Hemagglutinin (HA) gene sequences of influenza A viruses (IAVs) available from the GISAID and GenBank were aligned by MEGA 7.0 and then analyzed by WebLogo3 (http://weblogo.threeplusone.com/)Back to article page
