Integration of S·Protein-TP in the H5 oligomers. H5-S·Tag proteins were purified from plant extracts containing co-expressed proteins: S·Protein-TP (without His tag) and H5-S·Tag by IMAC. The purified product was analyzed by anti-c-myc tag Western blot. The presence of S·Protein-TP band shows the binding between S·Protein-TP and H5-S·Tag to form H5 oligomers.
