NR-50170?? Plasmid pMRLB.7 Containing Gene Rv3875 (Protein ESAT-6) from Mycobacterium tuberculosis(Plasmid/Vectors)|Mycobacterium tuberculosis|Plasmid pMRLB.7 Containing Gene Rv3875 (Protein ESAT-6) from Mycobacterium tuberculosis|-80°C or colder|BEI ResourcesAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Plasmid pMRLB.7 Containing Gene Rv3875 (Protein ESAT-6) from Mycobacterium tuberculosis, NR-50170."|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-50170 is a recombinant expression vector containing Mycobacterium tuberculosis gene Rv3875, which encodes the early secretory antigenic target ESAT-6, also known as esxA. Gene Rv3875 was amplified by PCR and cloned into pET23b for expression in Escherichia coli. The gene was cloned without a signal sequence and with nucleotides coding for the amino acids phenylalanine, alanine, leucine and glutamic acid (FALE) prior to the histidine tag. These nucleotides increase plasmid stability and promote solubility upon transformation and expression. The expressed protein has an observed molecular weight of 10 kDa.
Note: Plasmid pMRLB.7 contains the gene required for ampicillin (Ap) resistance. The recommended concentration of Ap in culture is 100 ?g/mL.
Each vial contains approximately 50 ?L of plasmid DNA in TE buffer (10 mM Tris-HCl, 1 mM EDTA, pH 8).

主要内容
此项目的每个订单数量限制为1.此商品每年可订购两次.此限制的订单将在发货前发送到NIAID批准.
NR-50170是一种重组表达载体,其含有分枝杆菌结核分枝杆菌(Thercobacterium Cherciry),其编码早期分泌抗原靶ESAT-6,也称为ESXA.通过PCR扩增基因RV3875并克隆到PET23B中,用于在大肠杆菌中表达.在组氨酸标签之前克隆没有信号序列,并且在组氨酸标签之前编码氨基酸亚丙氨酸,丙氨酸,亮氨酸和谷氨酸(FALE)的核苷酸.这些核苷酸增加质粒稳定性并在转化和表达时促进溶解性.表达的蛋白质观察到的分子量为10kDa.
注意:质粒pMRLB.7含有氨苄青霉素(AP)抗性所需的基因.培养中推荐的AP浓度为100μg/ ml.
每个小瓶在Te缓冲液中含有大约50μl质粒DNA(10mM Tris-HCl,1mM EDTA,pH 8).
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。
