The hemagglutinin (HA) gene is mapped to segment 4 of Influenza B viral genome. HA is a dominant antigen present on the influenza viral surface. It is a homotrimer and each monomer is produced as a single polypeptide.
Synonyms: Human influenza hemagglutinin amino acids 98-106
Storage: -20C
Application: Anti-HA-Tag antibody, Rabbit Monoclonal has been used in western blotting.
Biochem Physiol Actions: Hemagglutinin (HA) regulates membrane fusion and receptor-binding functions during viral entry and infection. The virus gains entry into the host cell via endocytosis and successive membrane fusion mediated by the HA antigen. HA plays a crucial role in viral pathogenesis and host response to viral infection.
