UBC9/UBE2I Protein, Human, Recombinant

产品编号 TMPY-02608

UBE2I is a member of the ubiquitin-conjugating E2 family whose members perform the second step in the ubiquitination reaction. Initially identified as the main process for protein degradation, ubiquitination is believed nowadays to be crucial for a wider range of cellular processes. The outcome of the ubiquitin-conjugation reaction, and thereby the fate of the substrate, is heavily dependent on the number of ubiquitin molecules attached and how these ubiquitin molecules are inter-connected. To deal with this complexity and to allow adequate ubiquitination in time and space, a highly sophisticated conjugation machinery has been developed. In a sequential manner, ubiquitin becomes activated by a ubiquitin-activating enzyme (E1), which then transfers the ubiquitin to a group of ubiquitin-conjugating enzymes (E2s). Next, ubiquitin-loaded E2s are interacting with ubiquitin-protein ligases (E3s) and ubiquitin is conjugated to substrates on recruitment by the E3. These three key enzymes are operating in a hierarchical system, wherein two E1s and 35 E2s have been found and hundreds of E3s have been identified in humans.

常见问题解答
产品的溶解度是多少?
建议您先查询TargetMol官网、陶术官网,看该抑制剂的产品介绍,找到溶解度信息。如果没有相应信息,建议联系技术对该化合物的溶解度进行测定。
溶解度写的“mg/mL”和“mM”是什么意思?
mg/mL 与 mM,是两种不同单位的表示方式,所指代的最大溶解度是一样的,可以通过官网网页下方的摩尔浓度计算器进行换算
得到的杀死细胞的 IC50 与网页上 IC50 差距较大怎么办?
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。
如何稀释工作液?
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!
母液配置的计算方法?
(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

存储
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式In general, Lyophilized powders are shipping with blue ice.
