General description

The gene encoding influenza virus hemagglutinin (HA) precursor is mapped on segment 4. It encodes a 76kDa surface glycoprotein which exists as trimers on the viral envelope.

Specificity

The antibody recognizes native as well as denatured-reduced forms of HA-tagged proteins and is reactive with N- or C-terminal HA-tagged fusion proteins expressed in E. coli or in mammalian cells.

Immunogen

synthetic peptide corresponding to a fragment of human influenza virus hemagglutinin (HA) known as HA-tag, conjugated to KLH

Application

Monoclonal Anti-HA antibody produced in mouse has been used in 293T cells for:
  • immunoprecipitation in human embryonic kidney 293 cells
  • immunoblotting in HeLa cells
  • immunopurification in human embryonic kidney 293 cells
  • immunostaining for electron microscopy in mouse embryonic fibroblasts
  • in immunocytochemistry of hippocampal slices
Monoclonal Anti-HA antibody produced in mouse has been used in:
  • Immunoblotting, to study the expression of fusion protein
  • Coimmunoprecipitation assay
  • Immunoblotting of lysate protein

Biochem/physiol Actions

Hemagglutinin (HA) is the surface glycoprotein of influenza virus. HA is crucial for virus entry and interaction with N-acetylneuraminic acid (Neu5Ac) in host cell surface. HA coordinates with neuraminidase (NA) and facilitates viral entry into host. HA exists as a trimer and each monomer has stalk transmembrane and globular regions. The globular region contains carbohydrate side chains crucial for infecting host.
Influenza virus hemagglutinin (HA) acts as a key immunogen in avian influenza virus (AIV) vaccines. Activated HA facilitates virus attachment to oligosaccharide receptors on host cell surface and is involved in penetration through fusion following conformational modifications in the endolysosomal compartment. 226 and 228 residues in hemagglutinin (HA) of the H3 subtype play a key role in host range restriction and receptor specificity. Influenza virus hemagglutinin (HA) is responsible for 1918 influenza pandemic.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month.
For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Solutions at working dilution should be discarded if not used within 12 hours.
