MRA-297??Plasmodium falciparum, Strain 3D7, 26-hour cDNA Library (Libraries)|Plasmodium falciparum|Plasmodium falciparum, Strain 3D7, 26-hour cDNA Library|-80°C|D ChakrabartiAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Plasmodium falciparum , Strain 3D7, 26-hour cDNA Library, MRA-297, contributed by Debopam Chakrabarti."|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.
This reagent was authenticated by the contributor. BEI Resources has not confirmed or validated this material.
Parasites were synchronized by a combination of Percoll flotation and sorbitol treatment. Total RNA samples were isolated from 26 hour (ring stage), saponin (0.1%)-lysed Plasmodium falciparum (P. falciparum), strain 3D7 infected erythrocytes by the acidic guanidinium-phenol chloroform method. The poly A+ RNA was isolated by the Promega polyAT-Tract mRNA isolation system using streptavidin Magnesphere particles. Directional cDNA libraries were constructed by oligo d(T) priming of poly(A)+ RNA (5 ?g) into EcoRI and XhoI sites of lambda ZapII vector using the Stratagene Zap cDNA synthesis kit. The average size of the cDNA inserts in the library was between 1.0 and 1.5 kb. Colonies from E. coli XL-1 blue MRF? cells harboring plasmid were obtained from lambda ZapII clones by in vivo excision with Stratagene ExAssist helper phage.

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。
