蛋白结构(Molecular Characterization)

Neuraminidase/NA (Influenza Virus) Structure

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

The protein has a calculated MW of 53.2 kDa. The protein migrates as 65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Supplied as 0.2 μm filtered solution in PBS, pH7.4, 300 mM NaCl with trehalose as protectant.

电泳(SDS-PAGE)

Neuraminidase/NA (Influenza Virus) SDS-PAGE

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

 

背景(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.
