NR-52511 contains a preparation of human (Homo sapiens) embryonic kidney cells (HEK-293T) constitutively expressing human angiotensin-converting enzyme 2 (ACE2). The HEK-293T-hACE2 cell line was created by transducing HEK-293T cells with lentiviral vector expressing ACE2 under the control of human elongation factor 1a (EF1a) promoter (BEI Resources NR-52512). Single transduced cells were sorted by flow cytometry as there is no antibiotic selection marker in the vector for mammalian expression and immunocytometry was required to identify cells expressing ACE2. Following identification of a clone expressing ACE2 at high levels, it was expanded. The expanded clone showed no noticeable decrease in expression of ACE2 through twelve passages; however, it is recommended that the cells undergo low levels of passages.
ACE2 is a human receptor that is expressed widely, including in heart, kidney, small intestine and lung cells, and is involved in the regulation of hypertension and other cardiovascular diseases. The SARS-Related Coronavirus 2 spike glycoprotein mediates viral binding to the host ACE2 receptor. This protein forms a trimer, and when bound to ACE2, allows fusion of the viral and cellular membranes, allowing viral entry and replication. The interaction of ACE2 and the spike glycoprotein during viral infection is currently under study.
Each vial contains approximately 1 mL of cell culture suspension frozen in Dulbecco’s Modified Eagle’s Medium (80%) containing fetal bovine serum (10%) and DMSO (10%) cryopreservative. Sufficient cells are provided to initiate at least one new culture.

NR-52511含有人类的制备（HOMO SAPIENS）（HOMO SAPIENS）胚胎肾细胞（HEK-293T）组成的人血管紧张素转换酶2（ACE2）. HEK-293T-HACE2细胞系通过在人伸长因子1A（EF1A）启动子（BEI资源NR-52512）的控制下用慢病毒载体转换HEK-293T细胞与慢病毒载体进行慢病毒载体（BEI资源NR-52512）.通过流式细胞术分选单个转导细胞，因为在哺乳动物表达的载体中没有抗生素选择标记，并且需要免疫细测定鉴定表达ACE2的细胞.在高水平下鉴定表达ACE2的克隆后，它被扩展.扩张的克隆表明ACE2至12个通道的表达没有明显减少;但是，建议细胞经历低水平的段落.
ACE2是一种人类受体，广泛表达，包括心脏，肾，小肠和肺细胞，并参与高血压和其他心血管疾病的调节. SARS相关的冠状病毒2穗糖蛋白介导病毒结合到宿主ACE2受体.该蛋白质形成三聚体，并且当与ACE2结合时，允许融合病毒和细胞膜，允许病毒进入和复制.在病毒感染期间ACE2和穗糖蛋白的相互作用目前正在研究中.
每个小瓶含有大约1ml的含有胎儿牛血清（10％）和DMSO（10％）冷冻保存的胎儿牛血清（80％）的细胞培养悬浮液.提供足够的细胞以引发至少一种新培养物.
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。
