Influenza A virus (A/Massachusetts/18/2022) NA(H3N2) Protein, His Tag (SPR verified)

  • Source
    Influenza A virus (A/Massachusetts/18/2022) NA(H3N2) Protein, His Tag (NEE-V524v) is expressed from human 293 cells (HEK293). It contains AA Lys 80 - Thr 469 (Accession # EPI2096147, GISAID).
    Predicted N-terminus: His
  • Molecular Characterization
    Neuraminidase/NA (Influenza Virus) Structure

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

    The protein has a calculated MW of 51.0 kDa. The protein migrates as 65-75 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

    Supplied as 0.2 μm filtered solution in 50 mM Tris, 500 mM NaCl, pH7.5 with trehalose as protectant.

SDS-PAGE
Neuraminidase/NA (Influenza Virus) SDS-PAGE

Influenza A virus (A/Massachusetts/18/2022) NA(H3N2) Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).

Bioactivity-SPR
 Neuraminidase/NA (Influenza Virus) SPR

a-Neu5Ac-PAA-biotin immobilized on SA Chip can bind Influenza A virus (A/Massachusetts/18/2022) NA(H3N2) Protein, His Tag (Cat. No. NEE-V524v) with an affinity constant of 92.7 nM as determined in a SPR assay (Biacore 8K) (QC tested).

  • 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.
