REG3B 重组蛋白, Mouse (His)

REG3B Protein, Mouse, Recombinant (His)

产品编号 TMPY-03673

Expression of REG3B was sufficient to inhibit cytokine-induced activation of STAT3 in IECs. The human REG3beta protein, the functional counterpart of mouse REG3B, inhibited STAT3 activity in human 293T cells, and its expression level in colorectal tumors correlated inversely with pSTAT3 level and survival times of patients. REG3B negatively regulates cytokine-induced activation of STAT3 in colon epithelial cells. This pathway might be targeted in patients with colitis to reduce carcinogenesis.

常见问题解答

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。

问抑制剂能否用于细胞实验？

答可以的，我们的抑制剂都可以用于细胞/体外实验。但有些化合物还没有用于细胞实验的文献，这种情况下，建议您先做预实验，确保研究的可行性。

问购买多次产品，发现颜色不同，怎么办？

答首先请您确认批次，如果是同一个批次产品，请联系技术同事核查产品颜色。如果是不同批次，请您放心，颜色不同可能是生产工艺不同而造成的，生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑，可在官网下载相应的质检报告，我们是对产品质量负责的。

问超声应使用什么样的频率？

答频率建议使用常规的超声清洗频率即可，一般在20 kHz - 100 kHz。

问收到产品发现冰盒都化了，怎么办？

答一般化合物粉末对温度不敏感，加冰盒是为了防止极端气温，如果冰盒融化不影响产品质量。

种属	Mouse
表达系统	HEK293 Cells
标签	C-His
蛋白编号	P35230
别名	REG-III,PAP1,Pap,HIP
蛋白构建	A DNA sequence encoding the mouse REG3B (NP_035166.1) (Met1-Gly175) was expressed with a C-terminal polyhistidine tag. Predicted N terminal: Glu 27
蛋白纯度	> 95 % as determined by SDS-PAGE
分子量	49.2 kDa (predicted); 19 kDa (reducing condition, due to glycosylation)
内毒素	< 1.0 EU/μg of the protein as determined by the LAL method.
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
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.
