蛋白名称：Neuraminidase/NA蛋白, Neuraminidase/NA protein
蛋白构建：A DNA sequence encoding the Influenza A virus (A/California/04/2009 (H1N1)) neuraminidase (ACP41107.1) (His 36-Lys 469) was expressed, the cell lysates are collected, and bio-activity was tested. There is an amino acid change from Histidine to Tyrosine (H275Y) in NA / Neuraminidase.
表达宿主：HEK293 Cells
蛋白纯度：0
蛋白活性：Measured by its ability to cleave a fluorogenic substrate, 2'-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid. The specific activity is > 200 U. One unit is defined as the amount of enzyme required to cleave 1 nmole of 2'-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid per minute at pH 7.5 at 37℃.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：0
蛋白分子量：The recombinant influenza A H1N1 Neuraminidase comprises 434 amino acids and has a predicted molecular mass of 47.8 kDa.
蛋白NP号：ACP41107.1
蛋白氨基酸序列：His36-Lys469
蛋白标签：Native
蛋白保存条件：Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
