| Description | D609 is an inhibitor of phosphatidylcholine specific phospholipase C (PC-PLC) with IC50 values of 94 µM. | |||||
| Targets | PC-PLC | |||||
| IC50 | 94 µM | |||||
| Cell experiment [1]: | |
Cell lines | HER2-overexpressing SKBr3 cells and various cancer cells |
Preparation method | The solubility of this compound in DMSO is > 12.7 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
Reacting condition | 50 μg/mL |
Applications | D609 inhibited PC-PLC, which enhanced HER2 internalization and lysosomal degradation, inducing down-regulation of HER2 expression on the membrane. Moreover, D609-induced PC-PLC inhibition significantly delayed HER2 re-expression on the membrane and reduced the overall cellular contents of HER2, HER2-HER3 and HER2-EGFR heterodimers. In addition, D609 also exhibited antiproliferative effects, especially in Trastuzumab-resistant cells, via PC-PLC inhibition. In breast cancer cells, D609 at the dose of 50 μg/mL decreased the activity of PC-PLC by 3.5 folds within 1hr. |

D609 is a specific and competitive inhibitor of phosphatidylcholine-specific phospholipase C (PC-PLC) with a Ki value of 6.4 μM. [1]
PC-PLC hydrolyzes (phosphatidylcholine) PC to generate 1, 2-diacylglycerol (DAG) and phosphocholine. D609 is a widely known inhibitor of PC-PLC and also inhibit sphingomyelin synthase (SMS). Due to these actions, it has antiviral and antitumor properties. D609 does not inhibit bacterial phosphatidylinositol (PI)-PLC, bovine pancreatic PLA2 or phospholipase D from cabbage[1b]. In OVCAR3 cells treated with (53 μg/mL) for 24 h, PC-PLC activity was significantly inhibited and cell proliferation was affected. In breast cancer cells, the activity of PC-PLC decreased 3.5 fold after the incubation with D609 (50 μg/ml) within 1h. The human epidermal growth factor receptor 2 (HER2) was also down-regulated [2]. D609 also has anti-inflammatory functions. It blocked the nitric oxide synthase induced by LPS (IC50=20 μg/mL) and IL-1β induced vascular cell adhesion molecule 1 gene expression in human endothelial cells.[3]
D609 can reduce sphingomyelin synthase, thereby it inhibits bFGF-stimulated astrocyte proliferation. Because of the presence of the thiol function, D609 also has antioxidant/glutathione mimetic properties[1b].

而且保真性要高一点的，因为今后要用来做表达
不过。。。。我时常用那种过期一两年的。。。。也能反转出来。只要你保存得当就可以了。一般是-20以下保存。
TERT是端粒酶逆转录酶
人的端粒酶是由端粒酶逆转录酶、端粒酶RNA和一种假尿嘧啶合成酶组成
在进行RT反应之前，应考虑以下几个方面：
1、RNA
成功的cDNA合成来自高质量的RNA，高质量的RNA至少应保证全长并且不含逆转录酶的抑制剂，如EDTA或SDS。在提取RNA的过程中，要特别防止RNase的污染，同时在逆转录反应中经常加入RNase抑制剂以增加cDNA合成的长度和产量。RNase抑制剂要在第一链cDNA合成反应中，在缓冲液和还原剂（如DTT）存在的条件下加入，因为cDNA合成前的过程会使抑制剂变性，从而释放结合的可以降解RNA的RNase。蛋白RNase抑制剂仅防止RNaseA，B，C对RNA的降解，并不能防止皮肤上的RNase，因此尽管使用了这些抑制剂，也要小心不要从手指上引入RNase，实验过程中经常更换新手套。
2、引物的选择
OligodT
选择OligodT时，要求RNA必须有PolyA，所以真核生物的mRNA都适用。适合长链甚至全长mRNA的RT，所以对RNA样品的质量要求较高，最好不要有明显的DNA污染、RNA降解和RNA断裂。假如想探索新的mRNA进行RT反应，建议推荐使用OligodT引物。使用OligodT引物要比随机引物和特异性引物的稳定性要好。
随机引物
适合各种RNA的RT，尤其适合模板丰度很低的情况（比如某个gene表达量很低）。选择随机引物时，第一链cDNA合成反应中就是以所有的RNA为模板，然后进行PCR反应时设计引物进行特异性扩增。同时要注意随机引物的量和总RNA量之间的关系，一般建议每5μg总RNA的随机引物的用量为50ng，如果每5μg总RNA的随机引物的用量超过250ng，可能会导致小片段产物（<500bp）的增加和长片断、全长产物产物的降低。
特异性引物
特异性引物只能用你设计引物时的下游引物做RT，引物设计质量影响RT的结果，而且不同引物退火温度本来就不相同，所以按照说明书按照一个温度做不是最佳选择，一般不推荐。向左转|向右转
