Biological Activity:
EPZ-5676 is a highly potent and selective inhibitor of DOT1L methyltransferase with Ki of 70 pM, selectively blocking the binding of the cofactor, S-adenosylmethionine. It inhibits proliferation of MLL-AF4 rearranged cell line MV4-11 with an IC50 of 9 nM. It reduces H3K79 dimethylation with a cellular IC50 of 2.6 nM in MV4-11 cells. EPZ-5676 has over 10,000-fold selectivity against other HMTs. Its superior potency is associated with its increased enzyme residence time and prolonged cellular effects after washout. It can reduce H3K79 methylation in all cells, but only kill cells with MLL rearrangement, making it a good drug candidate for cancer therapy. Now EPZ-5676 is in phase I clinical trials for advanced hematologic malignancies, including acute Leukemia with rearrangement of the MLL gene.
How to Use:
- In vitro: EPZ-5676 was used at 1 µM final concentration in vitro and in cellular assays.
- In vivo: Continuous intravenous infusion of EPZ-5676 at 70.5 mg/kg once per day for 21 days achieved complete tumor regressions in a nude rat subcutaneous xenograft model of MLL-rearranged leukemia.

我做的是细胞因子的刺激和抑制某条通路后观察是否有影响,分组为空白组,空白+抑制剂,刺激组,刺激+抑制剂,最开始用的单因素方差分析,LSD-T和SNK-Q检验,但是同学说我这里面有两个处理因素,所以不能单因素方差分析,应该直接空白和空白+抑制,空白和刺激,刺激和刺激+抑制剂进行独立样本T检验,现在脑子是混乱的,拜托园子里的大神们帮我看看,感激不尽!!
天然产物,大多都有颜色,
存在干扰,多数情况下需要做样品的阴性对照,
尽量能用荧光的方法,
之前我们做过,将两个试剂盒的方法合并后,做的,
效果还可以
支原体培养则是取样后在培养基上培养,看有多少支原体菌落会长出,是比较直观和可信的结果。
总体来讲,这两种检查手段可信度都较高,结合一起,不仅可以可靠的知道有无解脲支原体感染,还能知道感染是否严重。
该试剂盒是一种时间分辨的荧光共振能量转移免疫分析,该反应是一个竞争免疫反应,即铕标的cAMP示踪复合物与体系中的cAMP竞争结合标有Alexa Fluor 647染料的cAMP抗体。铕标cAMP示踪复合物是通过Biotin标记的cAMP与铕标的抗生物素蛋白链菌素(streptavidin)与抗体的复合物紧密结合产生的。
当抗体结合到示踪剂上时,340nm的激发光激发铕标分子,导致能量转移到Alexa Fluor 647染料上,结果产生665nm的发射光。荧光的强度与样品中的cAMP含量成反比。
本试剂盒用于检测在GPCR激动剂刺激下活细胞或者细胞膜制备品产生的cAMP。对于偶联Gαs的受体,激动剂刺激导致665nm的荧光强度降低,而拮抗剂则可以逆转这一效应;对于偶联Gαi的受体,在激动剂刺激的同时用forskolin刺激cAMP产生,那么激动剂则抑制forskolin诱导的cAMP的生成,因此对照只给forskolin的细胞组可以通过665nm荧光强度的增加反应激动剂的效应。
该试剂盒的灵敏度很高,室温下反应在20h内是稳定的。本试剂盒适用于在384孔板中进行24μl的微量分析。
1. 姜黄素是一个典型的HAT抑制剂。
2. 针对P300: 在大约10年前,Cole和他的同事设计出了一种p300/CBP抑制剂,发表在nature杂志上。
希望能帮到你,望采纳!
