NR-49697?? N8 Neuraminidase (NA) Protein from Influenza Virus, A/Jiangxi-Donghu/346/2013 (H10N8), Recombinant from Baculovirus(Proteins)|Influenza A virus| N8 Neuraminidase (NA) Protein from Influenza Virus, A/Jiangxi-Donghu/346/2013 (H10N8), Recombinant from Baculovirus|-20°C or colder|F KrammerAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: N8 Neuraminidase (NA) Protein from Influenza Virus, A/Jiangxi-Donghu/346/2013 (H10N8), Recombinant from Baculovirus, NR-49697."|Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.
A recombinant form of the N8 neuraminidase (NA) protein from influenza A virus, A/Jiangxi-Donghu/346/2013 (H10N8) was produced in Sf9 insect cells using a baculovirus expression vector system. The predicted ectodomain coding region of the NA gene was fused to a synthetic gene segment encoding an N-terminal six histidine tag followed by a tetramerization domain from vasodilator-stimulated phosphoprotein (VASP) and a thrombin cleavage site. The protein was purified by nickel affinity chromatography and then treated with thrombin to remove the tetramerization domain and the histidine tag. The thrombin-treated protein was further purified prior to final formulation. The full-length NA precursor protein is 470 residues (GISAID EpiFlu: EPI497479).
Each vial contains 50 ?g to 100 ?g of purified recombinant NA protein in 50 mM Tris buffer (pH 7.4) with 500 mM NaCl and 50% glycerol.
NR-49697 was demonstrated to be functionally active based on its ability to cleave the fluorogenic substrate 2’-(4-methylumbelliferyl)-α-d-N-acetylneuraminic acid (4-MUNANA).

厂牌介绍
BEI Resources 由美国国家过敏和传染病研究所 ( NIAID )成立,旨在为研究 A、B 和 C 类优先病原体、新兴传染病病原体、非病原微生物和其他相关微生物材料提供试剂、工具和信息到研究界。BEI Resources 获取、验证和生产科学家进行基础研究和开发改进的诊断测试、疫苗和疗法所需的试剂。通过将这些功能集中在 BEI Resources 中,可以监控科学界对这些材料的访问和使用,并确保试剂的质量控制。
除了为传染病界提供材料外,BEI Resources 还鼓励和支持研究人员和机构的材料存放。使用 BEI Resources存放材料对研究人员和研究社区有许多优势,包括安全存储、社区访问和分发;同时保护存款人的知识产权。只要有需要,BEI 资源库将作为研究人员的资源进行维护。您在 BEI Resources 的存款是一项有助于未来研究的长期投资。
BEI Resources 自 2003 年起由美国典型培养物保藏中心 (ATCC) 根据合同管理。2016 年 5 月, ATCC获得了一份为期七年的继续管理 BEI Resources的合同。合同范围已扩大到更全面的研究目录材料,包括由其他政府支持的研究项目存放的材料,将提供给生物防御和新兴传染病科学界。真菌、寄生虫、载体和其他相关材料已添加到现有的细菌、病毒和毒素试剂中,涵盖 NIAID A、B 和 C 类优先病原体和 NIAID 指定的新发传染病病原体和生物。
