title: Separation of hemagglutinin and neuraminidase from influenza virus membrane by column displacement electrophoresis (isotachophoresis) with preservation of their activities.
abstract: Triton X-100-solubilized membrane glycoproteins (neuraminidase and hemagglutinin) from purified equine influenza virus particles were separated by column displacement electrophoresis (isotachophoresis) in the presence of Pharmalyte spacers. Electrophoresis was performed in a 1.80 cm glass electrophoresis column with Sephadex G-25 Fine serving as supporting medium. Triton X-100 was present in the system to suppress protein aggregation. Neuraminidase and hemagglutinin activities were preserved and appeared in the electropherogram as separate peaks with some overlapping.
