ANTI-HA (12CA5)

Use Anti-HA (12CA5) for the detection of native influenza hemagglutinin protein and recombinant HA-tagged proteins using:

• Dot blots
• Immunochemistry
• Immunoprecipitation
• Western blotting

Note: For experiments in which sensitivity is not critical, use Anti-HA (12CA5). For higher sensitivity detection in western blotting at 10-fold lower concentration, use Anti-HA High Affinity (3F10).

Hemagglutinin HA is a dominant antigen present on the influenza viral surface. HA is a homotrimer, in which each monomer is produced as a single polypeptide. This monomer is cleaved into two subunits HA1 and HA2 by the host protease. The HA gene is mapped to segment 4 of influenza B viral genome.

Membrane fusion and receptor-binding action is the key function of hemagglutinin (HA) and it aids in viral entry and infection. HA is an influenza-virus glycoprotein that 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.
