Specifications

Our Abpromise guarantee covers the use of ab219897 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications

    SDS-PAGE

  • Form

    Lyophilised
  • Concentration information loading...

Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at 4°C (stable for up to 12 months). Store at -80°C. Avoid freeze / thaw cycle.

    pH: 7.40
    Constituents: 5% Trehalose, 95% PBS

    Lyophilized from 0.22 µm filtered solution.
    Note: 5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%.

  • Reconstitution
    It is recommended to reconstitute the lyophilized protein in sterile deionized water to a final concentration of 1 mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

General Info

  • Alternative names

    • Hemagglutinin
  • Relevance

    Hemagglutinin (HA) is a class I viral fusion protein from the Influenza virus. It is a major glycoprotein, comprising over 80% of the envelope proteins present in the virus particle. HA binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell, and is responsible for penetration of the virus into the cell cytoplasm by mediating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane. The HA protein is a homotrimer of disulfide-linked HA1-HA2. It also plays a major role in the determination of host range restriction and virulence. Genetic variation of hemagglutinin and/or neuraminidase genes results in the emergence of new influenza strains. Influenza A subtypes are classified based on the combination of the virus coat glycoproteins, hemagglutinin (HA) and neuraminidase (NA). H9N2 influenza A viruses circulate worldwide. Since the mid-1990s, H9 viruses have become adapted to land-based birds and have crossed sporadically to pigs and humans, causing mild respiratory disease. Importantly, some of the currently circulating H9N2 viruses bind to sialic acid receptors linked to galactose in the {alpha}-2,6 conformation, which is the preferential binding pattern of human influenza viruses. Thus, these H9N2 viruses possess one of the key elements needed to establish stable lineages in humans.
