NR-225??Toxoplasma gondii, ME49 (B7 clone)(Parasitic Protozoa)|Toxoplasma gondii|ME49 (B7 clone)|-130°C or colder (Note: Do not under any circumstances store vials at temperatures warmer than -70°C. Storage under these conditions will result in the death of the culture.)|LD SibleyAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Toxoplasma gondii, ME49 (B7 Clone), NR-225."|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.
Toxoplasma gondii (T. gondii), ME49 (originally isolated from a sheep in California and available as BEI Resources NR-362) was passed singly through a cat to obtain a line that was capable of producing oocysts, and then further cloned by limiting dilution to produce the B7 clone (also referred to as P and PLK strain).
Extensive testing of ME49, ME49 (B7 clone) and PTG (an independent clone of ME49) indicated that ME49 was effectively already a biological clone.
T. gondii, ME49 (B7 clone) is the Type II parental strain that was used in a genetic cross with the genotype Type III parental strain CTG ARA-SNF (also known as CTG ARA-AR/SNFR and CEP ARA-AR/SNFR and available as BEI Resources NR-10151) to test the feasibility of inter-strain crosses. Strain CTG ARA-SNF is the product of a genetic cross between singly resistant parental clones of the CTG (CEP) strain obtained by chemical mutagenesis.
T. gondii, ME49 (B7 clone) is commonly associated with AIDS. The whole genome shotgun sequence of ME49 (B7 clone) has been deposited in GenBank (ABPA01000000).
Note: This strain is also available as NR-10150 which has had additional characterization tests performed.
Each vial of NR-225 contains approximately 0.5 mL of culture in cryopreservative.

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进行批准. Toxoplasma Gondii(T.Gondii),ME49(最初从加利福尼亚州的羊群隔离和可用正如Bei Resources NR-362)单独通过猫通过,以获得能够产生卵囊的线,然后通过限制稀释来进一步克隆以产生B7克隆(也称为P和PLK菌株). 对ME49,ME49(B7克隆)和PTG(ME49的独立克隆的大量测试表明ME49有效地已经成为生物克隆. t. Gondii ,ME49(B7克隆)是II型亲本菌株,其与基因型III型亲本菌株CTG ARA-SNF的基因交叉(也称为CTG ARA-A R / snf r 和cep ara-a r / snf r 和作为bei资源nr-10151提供),以测试间歇的可行性压力交叉.菌株CTG ARA-SNF是通过化学诱变获得的CTG(CEP)菌株的被单抗性父母克隆之间的遗传交叉的产物. t. Gondii ,Me49(B7克隆)通常与艾滋病有关. ME49(B7克隆)的整个基因组霰弹枪序列已在Genbank(ABPA01000000)中沉积. > NR-225的每个小瓶中含有约0.5ml的冷冻保存培养物.
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。
