pIC50: 6.70 for human GPR35
CID-2745687 is a GPR35 antagonist. GPR35 is a poorly characterized member of the rhodopsinlike, class A subfamily of G protein-coupled receptors (GPCRs). GPCRs, based on the expression pattern, has been considered as a possible therapeutic target in conditions including diabetes, cardiovascular disease, as well as inflammation and pain.
In vitro: Previous study indicated that both CID-2745687 and ML-145 could competitively inhibit the effects of cromolyn disodium and zaprinast (two agonists sharing an overlapping binding site) on human GPR35. In contrast, though ML-145 antagonized the effects of pamoate competitively, CID-2745687 showed a noncompetitive fashion. Additionally, neither ML-145 nor CID-2745687 was able to antagonize the agonist effects at rodent ortholog of GPR35 [1].
In vivo: To test whether GPR35 contributes to the metabolic effect of Zaprinast, the retina from Cngb1/ mice was preincubated with a GPR35 antagonist, CID-2745687, followed by an additional Zaprinast treatment. Results showed that CID-2745687 did not block the effect of Zaprinast on glutamate and aspartate. Moreover, pamoic acid, the GPR35 agonist, did not change aspartate or glutamate levels [1].

还需要反转录用的引物、定量PCR用的一对引物、荧光信号源(荧光染料或荧光标记的探针,看你用什么策略来做定量PCR)
报价要看你需要服务商提供什么服务,如果你只提供实验材料,要求服务商做以上全部工作,只检测一个指标(一个基因的表达水平变化),价格大约每个样品350-500元,多一个指标大约多90元。
一般至少做一组数据两个样品嘛,所以你按1000块一组样品预算吧。
PCR(聚合酶链式反应)是利用DNA在体外摄氏95°高温时变性会变成单链,低温(经常是60°C左右)时引物与单链按碱基互补配对的原则结合,再调温度至DNA聚合酶最适反应温度(72°C左右),DNA聚合酶沿着磷酸到五碳糖(5'-3')的方向合成互补链。
恒温PCR和实时荧光定量PCR的不同,是不同在实时荧光定量PCR的系统中加入了荧光染料(SYBR Green 或Taqman 探针等等)。以SYBR Green为例,这种染料可以结合在双链的DNA上,当PCR不断进行时,每一次退火生成的双链DNA也在增加,荧光染料结合也越多,荧光也越强。在机器中有一个探测荧光的探头,可以定量检测荧光的强度,转换成数值。这样就可以实时记录反映体系中DNA的反应情况。
荧光PCR更有优势,因为荧光PCR灵敏度高于恒温PCR,同样价格也高一些。
如果要测量细胞表面2个受体的比率,最好用流式细胞仪来测量
荧光定量PCR较普通PCR不同的一点就是可以实时检测PCR扩增产物,从而可进行绝对定量或者相对定量。
一般有ROX Reference Dye和ROX Reference Dye II两种,针对不同的PCR仪.一般ABI PRISM 7000/7700/7900HT和7300 Real-Time PCR System使用ROX Reference Dye,而7500 Real-Time PCR System和7500 Fast Real-Time PCR System使用ROX Reference Dye II.其它牌子如Thermal Cycler Dice Real Time System、LightCycler 等Real Time PCR扩增仪时不必使用.
