说明 
 构建一个可以检测某一功能信号通路的细胞系,可以有助于解译参与这一信号通路的信号分子。这些工具载体是通过在载体的最小启动子的上游插入多个反应元件重复序列而获得的。我们提供含有三种经过改造的不同萤火虫萤光素酶基因(luc2 、luc2P 或luc2CP)的最小启动子载体。luc2 基因经过改造,去除了大部分隐藏的转录因子结合位点,并通过编码优化提高了在哺乳动物细胞中的表达效率。luc2P、luc2CP 和RapidResponse™  基因是在luc2 基因的基础上增加了降解序列,从而可以调控luc2 基因在细胞中的半衰期。RapidResponse™  基因对刺激的响应更快,但是以牺牲信号强度为代价。luc2P 基因( 半衰期为1 个小时) 反应比luc2 基因( 半衰期为3 个小时) 快,信号强度也适合,而luc2CP 基因( 半衰期为0.4个小时) 反应更快但信号强度最弱。最小启动子载体有含选择标签(hygromycin,潮霉素) 和不含选择标签的可供订购。为了提高实验效率,一些预设计的反应元件载体已经整合到了pGL4.27 载体中。其中一些载体也可订购其稳定表达的细胞系。
特点    • 基于以下原因拥有更好的灵敏度和生物相关性:
• 报告基因表达更高:为了更适于哺乳动物细胞的表达,将合成的基因密码子更加优化。
• 降低了表达产物的背景和危险:去掉了隐藏的DNA 调控元件和转录因子结合位点。
• 瞬时应答更快:Rapid Response™ 技术应用了去稳定萤光素酶基因。
其它的优势包括:
• 更灵活的检测选择:可随意选择合成luc2 (Photinus pyralis ) 或hRluc (Renilla reniformis ) 报告基因。
• 可轻松地从瞬时转换到稳定细胞:有多种哺乳动物细胞选择标记可供选择。
• 可轻松在载体间转移:具有常用的多克隆位点和独特的SfiI 转移设计。

货号: E8520      产品名称: GloResponse NF-kB-RE-luc2P HEK293 Cell Line   品牌: Promega 规格: 2 vials 二周到货 生化试验

说明  
 GloResponse™ Luciferase Cell Lines(GloResponse™ 萤光素酶细胞系) 经过优化,将最先进的萤光素酶报告基因技术整合入细胞系中。这样可以迅速开发新的检测方法,这些方法是基于目的信号转导通路对萤光素酶基因进行调控而设计的。使用GloResponse™细胞系形成的检测方法适用于高通量筛选。这些检测方法一般比其它检测方法具有更宽的反应动态范围( 诱导倍数),以及更好的质量,正如高Z` 值所示。GloResponse™ 细胞系可用于研究多种信号转导通路。这些信号通路的激活因子可以是HEK293 细胞系所固有的,如需研究非内源性的激活因子的活性,可将这些激活因子转染进入细胞后进行研究。
GPCR 能调控广泛的生物学功能,是药物发现中最重要的靶点之一。根据G 蛋白α 亚基的不同可把GPCR 信号通路分为三类:Gs,Gi/o 和Gq。GloResponse™ CRE-luc2P HEK293 Cell Line 可应用于Gs,Gi/o 偶联的GPCR( 其信号通过cAMP 和CRE 传导) 的研究,并可用其设定筛选用的检测方法。对于Gq 偶联的GPCR( 其信号通过钙离子释放和激活“活化T 细胞的核因子的反应元件,NFATRE”),应该使用GloResponse™ NFAT-RE-luc2P HEK293 Cell Line。
NF-κB-RE 是NF-κB 转录因子复合物的DNA 结合序列,负责调控炎症反应、免疫应答、细胞生长和细胞凋亡。GloResponse™ NF-κB-RE-luc2P HEK293 Cell Line 能够快速和方便地分析任何导致NF-κB 活性调节的细胞反应。
GloResponse™ 9XGAL4 UAS-luc2P HEK293 Cell Line 含有9个重复的GAL4 UAS( 上游激活序列),当有配基激活的时候,能够驱动萤光素酶报告基因luc2P 应答融合蛋白结合而产生的转录,该融合蛋白需要含有GAL4 DNA 结合域,比如pBIND-ERα 载体(Cat.#E1390) 上的雌激素受体配基结合域。这使得该细胞系适合研究核受体或者其他类型的蛋白: 蛋白以及蛋白: DNA 相互作用。必须使用转染或其它相似技术,将GAL4 DNA 结合域相结合的“蛋白伙伴”导入细胞内方可。
GloResponse™ Cell Lines 通过克隆筛选稳定转染pGL-4 载体的HEK293 细胞得到,该载体带有目的通路特异应答元件。这些细胞系整合了pGL4 报告基因载体家族的优势。去稳定化的luc2P 报告基因用于增强的转录动力学应答。luc2P 基因的密码子经过优化,以增强在哺乳动物细胞中的表达。pGL4 质粒的骨架也经过改造,降低本底表达。结果是,当目的信号通路被激活时,该细胞系就能被诱导产生高水平的反应。
特点 
 • 方便:细胞系是预先构建好的,并经过优化,带有萤光素酶报告基因。
• 强效:检测范围宽,诱导水平高,背景表达低。
• 快速:去稳定化的萤光素酶对转录调控的动态应答增强。。

 NF-κB Activation Inhibitor VII, CID-2858522
1-(3,5-di-tert-butyl-4-hydroxyphenyl)-2-(2-(3-hydroxypropylamino)-5,6-dimethyl-1H-benzo[d]imidazol-1-yl)ethanone; CID-2858522; 2-aminobenzimidazole; Compound 1a
A cell-permeable selective inhibitor of NF-κB activation induced by PKC pathway activators such as PMA (IC50 = 70 nM) in a HEK293 cell-based NF-κB luciferase reporter gene assay, by operating downstream of PKC but upstream of IKKβ, without inhibiting other NF-κB activation pathways. At 10 µM, this compound only inhibits Raf, TLK1, and JAK2 by 57%, 70%, and 53%, respectively, among a panel of 353 protein kinases. In addition, it attenuates CD3/CD28 and PMA/ionomycin-induced production of IL-2 by Jurkat T-cells (IC50 < 5 µM) and anti-IgM-stimulated proliferation of murine B-lymphocytes (IC50 = 2 µM).

NF-κB SN50, Cell-Permeable Inhibitor Peptide
AAVALLPAVLLALLAPVQRKRQKLMP, NF-κB Activation Inhibitor VIII
Contains the nuclear localization sequence (NLS) of the transcription factor NF-κB p50 linked to the hydrophobic region (h-region) of the signal peptide of Kaposi fibroblast growth factor (K-FGF). The N-terminal K-FGF h-region confers cell-permeability, while the NLS (360-369) inhibits translocation of the NF-κB active complex into the nucleus. In murine endothelial LE-II cells induced by LPS, NF-κB nuclear translocation is maximally inhibited at 18 µM.

CRAC Channel Inhibitor IV, EVP4593
N4-(4-phenoxyphenethyl)quinazoline-4,6-diamine, SOC Inhibitor
A cell-permeable quinazoline derivative that blocks PMA/PHA-induced NF-κB activation in Jurkat cells (IC50 = 11 nM), but has no effect on PKC kinase, and exhibits an anti-inflammatory effect on carrageenin-induced paw edema in rats (1 mg/kg, i.p.). In addition, it is shown to inhibit the store-operated calcium entry (SOC) pathway possibly by targeting TRPC1 containing heteromeric channels in Huntington Disease (HD) neurons (SK-N-SH cells transfected with mutant Huntingtin Htt-138Q) at 300 nM. It displays neuroprotective effects in YAC128 MSN mice neurons from glutamate toxicity dose-dependently from 30 nM to 3 µM, which is consistent with TRPC1 knockdown effects, and attenuates the progressive decline in the climbing speed of the HD Drosophila, dose-dependently from 100 µM to 400 µM.
