Chemical structure
| Cell experiment [1]: | |
Cell lines | J82 cells |
Preparation method | The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | 0–15 μM, 1h |
Applications | In J82 cells overexpressing FLAG-RalA, treatment with RBC8 for 1h reduced the activation of RalA. RBC8 dose-dependently inhibited cell spreading in WT MEF cells. RBC8 treatment inhibited colony formation in H2122 and H358 cell lines with the IC50 of 3.5 μM and 3.4 μM, respectively. |
| Animal experiment [1]: | |
Animal models | H2122 and H358 human lung cancer xenograft mice models |
Dosage form | Intraperitoneal injection, 50 mg/kg/d for 21 days |
Application | In mice bearing H358 and H2122 xenografts, RBC8 (50 mg/kg i.p.) inhibited tumor growth via specific inhibition of RalA and RalB. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

RBC8 inhibit Ral GTPase with IC50 values of 3.5 μM and 3.4 μM in Ral-dependent lines H2122 and H358 [1].
RalA and B are Ras-like GTPases. They are important drivers of metastasis and tumor growth [1].
RBC8 reduced the activation of RalA in living cells. Ral is required for spreading murine embryonic fibroblasts (MEFs) and lipid raft exocytosis on fibronectin-coated cover slips. In these cells, the spreading of WT MEFs was inhibited by the depletion of RalA via siRNA, whereas caveolin deficient (Cav1-/-) MEFs were resistant to RalA depletion. Treatment with RBC8 inhibited only the cell spreading in the WT MEFs, it did not inhibited the cell spreading in Cav1-/- MEFs. A Ral pull-down assay showed that RBC8 inhibited the activation of both RalA and RalB in both the H2122 and H358 cell lines. In H2122 and H358 cells with Ral knockdown by siRNA, treatment with RBC8 did not show further inhibition of colony formation [1].
In nude mice inoculated with H2122 human lung cancer cells subcutaneously, treatment with RBC8 at 50 mg/kg/d for 21 days (except weekends) intraperitoneally showed an inhibitory effect on tumor growth to a similar extent as dual knockdown of RalA and B. H358 is a lung cancer line. In this cell line, similar results were yielded [1].

**捷向您推荐美国Trevigen的一款通用PARP分析试剂盒检测试剂盒。该试剂盒是检测凋亡前与凋亡中细胞提取液中PARP活性的理想方案，操作简单，重复性高。其通过检测96孔板上生物素标记的多聚ADP核糖聚合到邻近组蛋白的反应，从而确定已知的或可能的PARP抑制剂。试剂盒中的依托泊苷（Etoposide）是拓扑异构酶Ⅱ抑制剂，在拓扑异构酶Ⅱ切割完DNA后能够稳定该酶。在试剂盒中，依托泊苷作为凋亡诱导的对照参与检测。
通量PARP/凋亡分析试剂盒可广泛应用于1）检测原代、肿瘤等细胞的PARP活性；2）检测凋亡前后的PARP活性；3）利用细胞裂解液筛选PARP抑制剂。
试剂盒特色比色法/化学发光法，无放射性输出。96well，高通量检测。极大地节省了分析时间，提高了使用效率。高敏感性。能够检测到500个细胞中低至0.1mU的PARP。检测范围广。0.1-10mU。样本用量少。仅仅需要10-100ng的提取物。检测时间短。仅需要3h即可完成检测。
**捷向您提供一站式的PARP相关实验解决方案，除了高通量PARP/凋亡分析试剂盒，还有PARP体内药理动力学二代分析试剂盒(PDAII)和通用PAPR分析试剂盒外(含组蛋白包被可拆卸板)，以及相关抗体和重组蛋白。

A.优点：
多重分析——一次分析可以检测16种干细胞相关的TF
定量比较——二个样本的差异可以定量分析和比较
步骤简单——探针温育、柱分离、板杂交和HRP检测
无需贵重仪器——无需如Luminex那样的贵重仪器
B.原理：
干细胞转录因子活性多重检测阵列试剂用于同时检测多种TF活性。该技术中，基于TFDNA结合位点的一致性序列，制备一系列生物素标记的探针。当探针混合物与核提取物一起温育时，每个探针寻找相应的TF，形成TF/探针复合物，通过柱离心纯化可以很容易与游离探针分开。结合的探针从混合物中分离出来，通过板杂交分析。板孔中预包被上与探针互补的特异序列，捕获的DNA探针进一步用链酶亲和素-HRP检测，化学发光检测仪测定发光强度（RLUs）。
