Biological Activity:
WDR5-C47 is a highly potent and selective antagonist of WDR5-MLL interaction with an IC50~0.3 µM. It was designed based on the structure of the WDR5-MLL complex. The WD40-repeat protein WDR5 plays a critical role in maintaining the integrity of the MLL complex and fully activating its methyltransferase function. The MLL complex, the trithorax-like family of SET1 methyltransferase, catalyzes trimethylation of lysine 4 on histone 3, and they have been widely implicated in various cancers. WDR5-C47 could serve as a tool compound to study functions of SET1-family of human histone methyltransferases and further develop therapeutic drug molecules targeting the WDR5−MLL interaction.
How to Use:
- In vitro: WDR5-C47 was suggested to be used at 10 µM final concentration in vitro and in cellular assays.
- In vivo:n/a

根据组成不同,可分为两种,弱酸及其对应的强碱弱酸盐,弱碱及其对应的强酸弱碱盐。
因为HF可以和NaOH反应生成NaF和水,当NaOH反应完之后,NaF就可以与HF组成缓冲溶液,所以说可以直接使用NaOH和HF来配制缓冲溶液。
这也是一般配制缓冲溶液的方法,也就是用强碱和弱酸(或者强酸和弱碱)来配制缓冲溶液。

酶提取技术,属地球化学勘查学科。其是由克拉克(J.R.Clark)等人于20世纪80年代末和90年代初研制出的一种利用葡萄糖氧化酶提取矿物颗粒表面的非晶质锰的氧化膜寻找隐伏矿的方法。1995年以后已广泛应用。
因为常用的缓冲溶液由弱酸及其共轭酸盐组合而成,当加入酸时,弱酸盐部分转化为弱酸;当加入碱时,弱酸部分转化为弱酸盐。而弱酸在水中不完全电离,弱酸盐在水中可以水解,所以ph变化较小,保持了溶液的PH基本不变。
