NR-45117大肠杆菌,单克隆抗志贺样毒素2亚基A,克隆11E10(体外生产)(单克隆抗体)

Antibody Class: IgG1κ
Mouse monoclonal antibody prepared against the A subunit of Shiga-like toxin 2 from Escherichia coli (E. coli) was purified from clone 11E10 (ATCC ? CRL-1907?) hybridoma supernatant by protein G affinity chromatography. The hybridoma cell line was generated by the fusion of SP2/0 myeloma cells with immunized mouse splenocytes.
The term Shiga toxin (Stx) refers to two families of related toxins: Shiga toxin/Shiga-like toxin 1 and Shiga-like toxin 2. Shiga toxin is produced by Shigella dysenteriae, while Shiga-like toxin 1 and Shiga-like toxin 2 are both produced by enterohemorrhagic strains of E. coli. Both Shiga and Shiga-like toxins are multimeric molecules that are comprised of two polypeptide subunits, A and B. The B subunit is a pentamer that binds to glycolipids on host cell membranes and the entire Stx molecule can then enter the cell via endocytosis. Once inside the cell, the Stx A subunit undergoes proteolytic cleavage and the reduction of an internal disulfide bond to generate Stx A1 and Stx A2. Stx A1 is an N-glycosidase that catalytically inactivates the 28S ribosomal RNA subunit to inhibit protein synthesis. The nucleotide sequence of the gene for the Shiga-like toxin 2 A subunit from E. coli has been reported (GenBank: AB035143).
NR-45117 is being released without confirmation of functional activity. The monoclonal antibody produced by hybridoma clone 11E10 has been reported to react with recombinant E. coli Shiga-like toxin 2 subunit A by ELISA and western blot.
Each vial of NR-45117 contains approximately 100 ?L of purified monoclonal antibody in PBS, pH 7.4.
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。
