Recombinant HIV-1 TAT Clade-B
英文简称:
HIV-1 TAT Clade-B
中文名称:
重组HIV-1 Tat蛋白,进化枝B
背景资料:
Human immunodeficiency virus type-1 (HIV-1) regulatory Tat protein plays an essential role in viral replication (Jones KA, 1994) and infectivity (Arya SK, 1985; Fisher AG, 1986). In addition, during acute infection, Tat is released extracellularly by infected cells (Chang HC, 1997; Ensoli B, 1990) and is taken up by neighboring cells where it transactivates viral replication (Ensoli B, 1993) and increases virus infectivity. HIV-1 Tat activates transcription of HIV-1 viral genes by inducing phosphorylation of the C-terminal domain (CTD) of RNA polymerase II (RNAPII). Tat can also disturb cellular metabolism by inhibiting proliferation of antigen-specific T lymphocytes and by inducing cellular apoptosis. Tat-induced apoptosis of T-cells is attributed, in part, to the distortion of microtubules polymerization. LIS1 is a microtubule-associated protein that facilitates microtubule polymerization.
产品描述:
HIV-1 TAT Recombinant- produced in E. Coli is a single, non-glycosylated, polypeptide chain containing 86 amino acids encoded by two exons and having chain having a molecular mass of 14kDa.

溶解建议:
提供的重组HIV-1 Tat蛋白,进化枝B产品为无菌冻干粉末形式.建议加无菌的18MΩ-cm水以配制工作储存液到不低于100ug/ml,后继实验过程中可根据实验要求进一步稀释.
保存建议:
Lyophilized HIV-1 TAT although stable at room temperature for 1 week, should be stored desiccated below -18℃. Upon reconstitution HIV-1 TAT should be stored at 4℃ between 2-7 days and for future use below -18℃. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
其他简介:
ProSpec是一家全球著名细胞因子蛋白及相关抗体生产和研发品牌。ProSpec的生产和研发工厂位于以色列,专注于蛋白(重组及合成)生产研发,其独有的细菌和哺乳动物表达和蛋白折叠技术使其能在17年内成长为国际一流的科研级蛋白供应商。目前ProSpec可以提供细胞因子,生长因子,激素,信号蛋白,病毒抗原等近800种重组蛋白和100多种抗体,是世界上提供蛋白品种最多的公司之一,领先的生产工艺和规模使其可以提供毫克到克级蛋白,价格优于同类公司。绝大部分产品是天然成熟型蛋白,而不含有标签蛋白。考虑到大部分研究者希望能更灵活地配制蛋白溶液,ProSpec-Tany绝大部分产品没有添加保护剂或盐,这就对工艺提出了更高的要求。同时,ProSpec-Tany绝大部分产品为冻干粉,因此易于运输和保存。

文献和实验liufengxi HIV-1 Tat (47-57) N-term Cys 序列 H-CYGRKKRRQRRR-NH2 ;原始HIV-1 Tat (47-57)序列为YGRKKRRQRRR 。N端的半胱氨酸修饰是为了利用其含有的巯基和其他分子反应,但是C端得-NH2的修饰是什么目的呢?有这个修饰的必要吗?是为了增强多肽的活性,还是发挥一个阻断活性COOH的作用? 附件是关于HIV-1 Tat (47-57) N-term Cys的产品介绍。请高手
