HA/Hemagglutinin, H3N2 (P03437, sf9, His)

HA/Hemagglutinin Protein binds to cell surface receptors, facilitating virus attachment.It determines host range and virulence.As a class I fusion protein, it mediates fusion of virus and endosomal membranes for cell penetration.Acidic endosomes trigger HA2 conformational change, releasing fusion peptide.Multiple HA trimers are needed for fusion pore formation.HA/Hemagglutinin Protein, H3N2 (P03437, sf9, His) is the recombinant Virus-derived HA/Hemagglutinin protein, expressed by Sf9 insect cells , with C-His labeled tag.
