分子别名（Synonym）:NA

种属（Species）：H1N1

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, 0.6% Triton X-100, 7% Trehalose, 6% Mannitol, pH 7.4

分子量（Molecule Mass）：The recombinant influenza A H1N1 Neuraminidase comprises 469 amino acids and has a predicted molecular mass of 52 kDa.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：Measured by its ability to cleave a fluorogenic substrate, 2'-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid.

表达区间（Protein Construction）：A DNA sequence encoding the Influenza A virus (A/California/04/2009 (H1N1)) neuraminidase (ACP41107.1) (Ser 2-Lys 469) was expressed, the cell lysates are collected, and bio-activity was tested. There is an amino acid change from Asparagine to Serine (N295S mutation) in NA / Neuraminidase.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
