abstract：:The M2 protein of influenza A H1N1 strains PR8, WS, and WSN is present in homooligomeric forms in virions grown in the allantoic cavity of embryonated eggs. The bulk of the virion M2 is detected as tetramers and dimers. The oligomeric forms of PR8 virions differ from those of WS and WSN not only in apparent molecular ...
