NR-21973??Human respiratory syncytial virus, Human Reference Immune Globulin to Respiratory Syncytial Virus, CBER RSV Lot 1(Polyclonal Antiserum)|Human respiratory syncytial virus|Human Reference Immune Globulin to Respiratory Syncytial Virus, CBER RSV Lot 1|-20°C or colder|U.S. Food and Drug AdministrationAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Human Reference Immune Globulin to Respiratory Syncytial Virus, CBER RSV Lot 1, NR-21973."|Quantity limit 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.
Human plasma was obtained from normal healthy donors, some of whom had probably been infected with respiratory syncytial virus (RSV) in the past. The immune globulin was purified from the plasma pools using a modified Cohn-Oncley cold ethanol fractionation process, as well as cation and anion exchange chromatography. The immune globulin was further treated to remove or inactivate viruses using solvent detergent treatment (with tri-n-butyl phosphate, octoxynol 9, and polysorbate 80 at 18°C to 25°C for a minimum of 60 minutes), 35 nm filtration and low pH incubation at an elevated temperature. The final immune globulin (10%) is a sterile 100 mg/mL protein preparation stabilized with 0.25 M glycine (pH 4.6 to 5.1). At least 98% of the protein was determined to be immune globulin. The osmolality was determined to be 240 to 300 mOsmol/kg.
Each vial contains approximately 2 mL of immune globulin (10%) in 0.25 M glycine (pH 4.6 to 5.1).
Note: Dilute 1:10 to a final concentration of 1% immune globulin in sterile PBS (pH 7.4) prior to testing in virus neutralization assays.
NR-21973 is also available as part of a Panel of Human Antiserum and Immune Globulin to Respiratory Syncytial Virus (BEI Resources NR-32832).

主要内容
此项目的数量限制为1.此商品可以每年订购两次.此限制的订单将在发货前发送到NIAID进行批准. 人类血浆是从正常健康的捐赠者获得的,其中一些人可能已经感染了过去呼吸道同性恋病毒(RSV) .使用改性的COHN-甲烷冷乙醇分馏方法以及阳离子和阴离子交换色谱法从血浆池中纯化免疫球蛋白.进一步处理免疫球蛋白以使用溶剂洗涤剂处理(用三叔丁基磷酸盐,octoOxynol 9和聚山梨醇酯80在18℃至25℃下最少60分钟),35nm过滤和灭活病毒在升高的温度下孵育低pH.最终的免疫球蛋白(10%)是稳定0.25m甘氨酸(pH4.6至5.1)稳定的无菌100mg / ml蛋白质制剂.至少98%的蛋白质被确定为免疫球蛋白.测定渗透渗透压为240至300 mosmol / kg. 每个小瓶含有大约2ml的免疫球蛋白(10%),在0.25 m甘氨酸中(pH4.6至5.1). 注意事项:在病毒中和测定试验之前,在无菌PBS(pH7.4)之前将1:10稀释至无菌PBS(pH7.4)中的1%免疫球蛋白. NR-21973也可作为人类抗血清小组的一部分提供免疫球蛋白到呼吸道合胞病毒(Bei Resources NR-32832 ).
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。
