NR-53589?? Spike Glycoprotein (Stabilized) from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine and Twin-Strep? Tags, Recombinant from HEK293 Cells(Proteins)|SARS-Related Coronavirus 2|Spike Glycoprotein (Stabilized) from SARS-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine and Twin-Strep? 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-Related Coronavirus 2, Wuhan-Hu-1 with C-Terminal Histidine and Twin-Strep? Tags, Recombinant from HEK293 Cells, NR-53589.”|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-related coronavirus 2 (SARS-CoV-2), Wuhan-Hu-1 (GenPept: QHD43416) was produced by transient transfection of a previously published construct (VRC7471) into human embryonic kidney HEK293 cells and purified by immobilized metal affinity and gel filtration chromatography. NR-53589 lacks the native signal sequence and contains 1194 residues (ectodomain) of the SARS-CoV-2 S glycoprotein; the recombinant protein was stabilized by substitution at the furin S1/S2 cleavage site (RRAR→GSAS; residues 682 to 685) and KV→PP mutations (residues 986 and 987), and includes a T4 foldon trimerization domain, HRV3C protease cleavage site, and C-terminal octa-histidine and Twin-Strep? tags. NR-53589 has a theoretical molecular weight of 140,700 daltons. The crystal structure for trimeric S glycoprotein from SARS-CoV-2 has been solved at 3.46 ? resolution (PDB: 6VSB).
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-53589 in 10 mM HEPES, pH 7, 150 mM NaCl and 2 mM ethylenediamine-tetraacetic acid (EDTA).

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。
