  • Source
    Influenza B (B/Singapore/WUH4618/2021) Hemagglutinin (HA) Protein, His Tag (HAE-V52H6) is expressed from human 293 cells (HEK293). It contains AA Asp 16 - Thr 552 (Accession # EPI1885132, GISAID).
    Predicted N-terminus: Asp 16
  • Molecular Characterization
    Hemagglutinin (HA) Structure

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 60.2 kDa. The protein migrates as 80-110 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Background
    Neuraminidase (NA) and hemagglutinin (HA) are major membrane glycoproteins found on the surface of influenza virus. Hemagglutinin binds to the sialic acid-containing receptors on the surface of host cells during initial infection and at the end of an infectious cycle. Hemagglutinin also plays a major role in the determination of host range restriction and virulence. As a class I viral fusion protein, hemagglutinin 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.
