分子别名(Synonym)

NA,Neuraminidase

表达区间及表达系统(Source)

Influenza A [A/Thailand/1(KAN-1)/2004 (H5N1)] NA, His Tag (H54-V5247) is expressed from human 293 cells (HEK293). It contains AA His 36 - Lys 449 (Accession # H8PF47).

Predicted N-terminus: His

蛋白结构(Molecular Characterization)

Online(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 50-57 kDa 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)

>92% as determined by SDS-PAGE.

制剂(Formulation)

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

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.
