Source

Influenza A [Wisconsin/67/2022(H1N1)] Neuraminidase (NA) Protein, His Tag (NEE-V524m) is expressed from human 293 cells (HEK293). It contains AA Ser 31 - Asn 469 (Accession # EPI_ISL_15928538, GISAID).

Molecular Characterization

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

The protein has a calculated MW of 56.4 kDa. The protein migrates as 55 kDa, 65 kDa and 80-95 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 / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

Supplied as 0.2 μm filtered solution in 50 mM Tris, 300 mM NaCl, pH7.5 with trehalose as protectant.

Background Introduction

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.
