NR-52422?? Vector pcDNA3.1(-) Containing the SARS-Related Coronavirus 2, Wuhan-Hu-1 Spike Glycoprotein Receptor Binding Domain (RBD)(Plasmid/Vectors)|SARS-Related Coronavirus 2|Vector pcDNA3.1(-) Containing the SARS-Related Coronavirus 2, Wuhan-Hu-1 Spike Glycoprotein Receptor Binding Domain (RBD)| -20°C or colder|D VeeslerAcknowledgment for publications should read “The following reagent was contributed by David Veesler for distribution through BEI Resources, NIAID, NIH: Vector pcDNA3.1(-) Containing the SARS-Related Coronavirus 2, Wuhan-Hu-1 Spike Glycoprotein Receptor Binding Domain (RBD), NR-52422. Work making use of this reagent should also cite Walls, A. C. and Y.-J. Park, et al. Cell 181 (2020): 281-292. PubMed: 32155444.”|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.
The vector for the spike (S) glycoprotein receptor binding domain (RBD; also referred to as SB) from severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), Wuhan-Hu-1 (GenBank: MN908947) was designed by codon optimizing the spike RBD (amino acids 328 to 531) for mammalian expression, fused to an N-terminal mu-phosphatase signal sequence and C-terminal octa-histidine tag, and subcloned into the pcDNA?3.1(-) mammalian expression vector. NR-52422 contains the beta-lactamase gene, TEM-116, to provide transformant selection through ampicillin resistance in Escherichia coli (E. coli), and a neomycin (G418) selectable marker for mammalian expression. The resulting size of the plasmid is approximately 6120 base pairs. The complete plasmid sequence and map are provided on the BEI Resources webpage. The plasmid was produced in E. coli and extracted.
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 of lot 70035172 contains 0.4 ?g of plasmid DNA in 10 mM Tris-HCl, 1 mM EDTA, pH 8.0. The vial should be centrifuged prior to opening. Note: The contents of the vial should be used to replicate the plasmid in E. coli prior to mammalian expression.

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。
