Figure 5From: Neutralizing immune responses induced by oligomeric H5N1-hemagglutinins from plants Oligomeric H5 formation, as demonstrated by size exclusion chromatography, hemagglutination and Western blot analyses. IMAC-purified H5 oligomers or H5-S·Tag (each 34 µg in 0.5 mL) were separated on Superose™ 6 increase 10/300 GL, and the fractions were analyzed by hemagglutination assay (A) and Western blot (B).Back to article page
