Molecular Weight

The secreted recombinant hemagglutinin of influenza A virus H5N1 (A/Hubei/1/2010) comprises 525 amino acids and has a predicted molecular mass of 60.1 kDa. As a result of glycosylation, it migrates as an approximately 65-70 kDa band in non-reduced SDS-PAGE, and three bands (25, 45, 70 kDa) in reduced SDS-PAGE.
