The HA/hemagglutinin protein is critical in the viral life cycle, binding to sialic acid receptors and facilitating viral attachment to host cells. This interaction promotes virion internalization through clathrin-dependent or -independent pathways. HA/Hemagglutinin Protein, H5N1 (H8PF45, HA1, HEK293, His) is the recombinant Virus-derived HA/Hemagglutinin protein, expressed by HEK293 , with C-His labeled tag.
