Recombinant Influenza A [A/Thailand/1(KAN-1)/2004 (H5N1)] Neuraminidase (NA)

  • Synonym
    NA,Neuraminidase
  • Source
    Influenza A [A/Thailand/1(KAN-1)/2004 (H5N1)] NA (H54-V5247) is expressed from human 293 cells (HEK293). It contains AA His 36 - Lys 449 (Accession # H8PF47).
    Predicted N-terminus: His 36
  • Molecular Characterization
    Neuraminidase (NA)(His 36 - Lys 449) H8PF47

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

    The protein has a calculated MW of 46.1 kDa. The protein migrates as 48 kDa under reducing (R) condition (SDS-PAGE).

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

    >92% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Influenza A [A/Thailand/1(KAN-1)/2004 (H5N1)] NA (Cat. No. H54-V5247) SDS-PAGE gel

Influenza A [A/Thailand/1(KAN-1)/2004 (H5N1)] NA on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 92%.

  • 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. Neuraminidase, on the other hand, cleaves the HA-sialic acid bondage from the newly formed virions and the host cell receptors during budding. Neuraminidase thus is described as a receptor-destroying enzyme which facilitates virus release and efficient spread of the progeny virus from cell to cell.
