EBP1 Protein, Human, Recombinant (His)

产品编号 TMPY-02844

EBP1, also known as PA2G4, is an RNA-binding protein that belongs to the peptidase M24 family. It can be detected n several cell lines tested, including primary and transformed cell lines. EBP1 also present in pre-ribosomal ribonucleoprotein complexes and may be involved in ribosome assembly and the regulation of intermediate and late steps of rRNA processing. This protein is a transcriptional co-repressor of androgen receptor-regulated genes and other cell cycle regulatory genes through its interactions with histone deacetylases. PA2G4 can interact with the cytoplasmic domain of the ErbB3 receptor and may contribute to transducing growth regulatory signals. EBP1 has been implicated in growth inhibition and the induction of differentiation of human cancer cells. It seems to be involved in growth regulation. EBP1 also mediates cap-independent translation of specific viral IRESs (internal ribosomal entry site).

常见问题解答

问超声久了会不会对化合物的结构有影响？

答建议以较低频率对化合物进行超声，不会对化合物的结构造成影响。

问是否能直接用缓冲液对抑制剂 DMSO 母液做梯度稀释？

答大部分情况下，都是可以溶解的。但有时，有机试剂直接加入水相介质时会析出。建议将抑制剂先以DMSO做梯度稀释，再将经过稀释的抑制剂加入缓冲液或细胞培养基。有些抑制剂甚至只有在其工作浓度下才能溶于水相。比如细胞实验中希望终浓度为 1 μM 的话，可以把 10 mM 的 DMSO 母液用 DMSO 稀释到 1 mM，再吸 2 μL 加入到 2 mL 的生理盐水/PBS/细胞培液，终浓度即为 1 μM。为避免药物析出，稀释前，可将母液和培养基 37℃ 预热，避免温度低造成严重析出。若稀释过程中出现化合物析出的情况，建议您采用超声加热的方法使其复溶。

问如何稀释工作液？

答根据您的工作液浓度，计算母液所需要稀释的倍数和所需母液的体积。建议用水、生理盐水、PBS等溶剂进行稀释，如果是细胞实验，可以使用培养基。取适当的溶剂缓慢加入到母液中，直到达到您的工作液浓度，可以通过涡旋或者移液枪轻轻吹打帮助混匀。我们的化合物大部分是脂溶性的，所以在使用 PBS 或者培养基等稀释工作液的时候，会有沉淀析出，这些都是正常现象，大多时候可以通过超声完全溶解。工作液建议现配现用！

问母液配置的计算方法？

答（1） c=n/v=m/M/v 浓度=物质的量/体积=质量/相对分子质量/体积（2）官网产品详情页下方有溶液配制表格，可以参考计算好的加入溶剂体积

问得到的杀死细胞的 IC50 与网页上 IC50 差距较大怎么办？

答您所测试的IC50是指细胞的增殖抑制实验（半抑制率），细胞增殖抑制实验 IC50值，和网页上的靶点IC50其实是不同的意义。文献里和网页上 IC50其实往往是指对于靶点无细胞实验的抑制率，这样的实验一般是通过激酶或者蛋白纯化实验做出来的，nM 级别的浓度比较常见，但是细胞的增殖抑制实验 IC50 是指细胞的半致死率，同时牵涉到细胞的代谢以及渗透，一般浓度会高一些。另外，同一个化合物对不同细胞模型的效果也是不同的，建议尝试增加孵育量、延长孵育时间。
