产品描述信息
NR-14838??Mycobacterium tuberculosis, CDC1551, Total Lipids(Antigen Preparations)|Mycobacterium tuberculosis|CDC1551, Total Lipids|Room temperature|BEI Resources or NIH - TB Vaccine Testing and Research Materials ContractAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Mycobacterium tuberculosis, Strain CDC1551, Total Lipids, NR-14838."|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.
NR-14838 is a preparation of the total cellular lipids of irradiated Mycobacterium tuberculosis, strain CDC1551, including those with known biological activities, such as trehalose dimycolate (TDM) and sulpholipids. The culture was grown to late-log phase in glycerol-alanine-salts medium, washed with PBS, inactivated by gamma irradiation and dried. The cellular lipids were extracted with 30 mL of chloroform/methanol (2:1) per gram of cells at 55°C for 18 hours. Cells were removed by filtration and contaminating hydrophilic molecules were removed by biphasic partitioning with water (Folch Wash). The organic phase of the Folch wash was collected and dried.
Each vial contains approximately 5 mg of dried, purified total lipids from Mycobacterium tuberculosis, strain CDC1551.
Note: Total lipid is soluble in chloroform:methanol (2:1). Chloroform or DMSO can also be used depending on the downstream application.

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。
