NR-53590?? Spike Glycoprotein (Stabilized) from SARS Coronavirus, Tor2 with C-Terminal Histidine and Strep? II Tags, Recombinant from HEK293 Cells(Proteins)|SARS Coronavirus|Spike Glycoprotein (Stabilized) from SARS Coronavirus, Tor2 with C-Terminal Histidine and Strep? II Tags, Recombinant from HEK293 Cells| -20°C or colder|DN Sather, P Myler, J McLellanAcknowledgment for publications should read “The following reagent was obtained through BEI Resources, NIAID, NIH: Spike Glycoprotein (Stabilized) from SARS Coronavirus, Tor2 with C-Terminal Histidine and Strep? II Tags, Recombinant from HEK293 Cells, NR-53590.”|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 spike (S) glycoprotein from severe acute respiratory syndrome coronavirus (SARS-CoV), Tor2 (GenPept: NP_828851) was produced by transient transfection into human embryonic kidney HEK293 cells and purified by immobilized metal affinity and gel filtration chromatography. NR-53590 lacks the signal sequence and contains 1177 residues (ectodomain) of the SARS-CoV S glycoprotein; the recombinant protein was stabilized by KV→PP mutations (residues 968 and 969), and includes a T4 foldon trimerization domain, HRV3C protease cleavage site, and C-terminal octa-histidine and Strep? II tags. NR-53590 has a theoretical molecular weight of 137,136 daltons. The crystal structure for trimeric S glycoprotein from SARS-CoV has been solved at 3.30 ? resolution (PDB: 6CRZ).
The S glycoprotein mediates viral binding to the host angiotensin converting enzyme 2 (ACE2). This protein forms a trimer, and when bound to a host receptor, allows fusion of the viral and cellular membranes. The S protein is a target for neutralizing antibodies.
Each vial contains approximately 100 ?L of NR-53590 in 10 mM HEPES, pH 7, 150 mM NaCl and 2 mM ethylenediamine-tetraacetic acid (EDTA).

主要内容
此项目的每个订单数量限制为1.此商品每年可订购两次.此限制的订单将在发货前发送到NIAID批准.
来自严重急性呼吸综合征冠状病毒(SARS-COV),Tor2(Genpept: NP_828851 ”是通过瞬态转染到人胚胎肾HEK293细胞中,并通过固定化金属亲和力和凝胶过滤色谱纯化. NR-53590缺少信号序列并含有1177个残基(Ectodomain)的SARS-COV S糖蛋白;通过KV→PP突变(残基968和969)稳定重组蛋白,并包括T4粘性三聚体化结构域,HRV3C蛋白酶切割位点和C末端Octa-modeatine和 Strep ? ii标签. NR-53590具有理论分子量为137,136道尔顿. SARS-COV三聚糖蛋白的三聚体S糖蛋白的晶体结构已在3.30埃分辨率(PDB: 6crz ).
S糖蛋白介导与宿主血管紧张素转化酶2(ACE2)的病毒结合.该蛋白质形成三聚体,并且当与宿主受体结合时,允许融合病毒和细胞膜. S蛋白是中和抗体的靶标.
每个小瓶在10mM Hepes,pH 7,150mM NaCl和2mM乙二胺 - 四乙酸(EDTA)中含有约100μl的NR-53590.
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。
