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 transfection of purified plasmid in Chinese hamster ovary (CHO) cells, purified by immobilized nickel affinity chromatography and dialyzed into buffer. NR-53769 lacks the 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) as well as the additional proline substitutions that create the HexaPro variant (F817P, A892P, A899P and A942P), and includes a T4 foldon trimerization domain, HRV3C protease cleavage site, and C-terminal octa-histidine and Twin-Strep? (TST) tags. NR-53769 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 80 ?L of NR-53769 in 20 mM Tris, pH 8.0 and 500 mM NaCl.

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相关的冠状病毒2（SARS-COV-2），武汉-U-1（Genpept：）通过在中国仓鼠卵巢（CHO）细胞中纯化质粒来制备，通过固定化镍亲和层析纯化并透析到缓冲液中. NR-53769缺少信号序列，含有1194个残基（Ectodomain）的SARS-COV-2S糖蛋白;通过在Furin S1 / S2切割位点（RrAR→GSAs;残基682至685）和KV→PP突变（残基986和987）以及产生己叠变体的另外的脯氨酸取代（F817P），通过取代稳定重组蛋白，A892P，A899P和A942P），包括T4 Folcon三聚化结构域，HRV3C蛋白酶切割位点和C末端Octa-组氨酸和双-Step ?（tst）标签. NR-53769具有140,700道尔顿的理论分子量. SARS-COV-2中三聚糖蛋白的晶体结构已在3.46埃分辨率（PDB： 6vsb ）.
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20mM Tris，pH 8.0和500mM NaCl中含有大约80μl的NR-53769.

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。
