IL-7R alpha/CD127 Protein, Mouse, Recombinant (hFc)

产品编号 TMPJ-00284

Interleukin 7 Receptor alpha (IL-7Rα), also known as CD127, is a 75 kDa hematopoietin receptor superfamily member that plays an important role in lymphocyte differentiation, proliferation, and survival. IL-7Rα is majorly expressed on T cells and their precursors, and early in B cell development as well, prior to the appearance of surface IgM. Dynamic regulation of IL-7Rα is important for the generation of appropriate immune responses. IL-7R alpha/CD127 Protein, Mouse, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-Fc tag. The predicted molecular weight is 61-75 KDa and the accession number is P16872.

实验操作小课堂
常见问题解答
收到粉状试剂粘壁严重,如何处理?
建议您用离心机 3000 rpm下离心一会儿,将粉末收集到管底。
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。
动物不能耐受 DMSO,给药时 DMSO量应该如何控制?
对于普通的老鼠,DMSO 的浓度应控制在 10% 以下,对于裸鼠、转基因小鼠、耐受性弱的老鼠等,DMSO 浓度需控制在2%以下。对于首次操作的抑制剂,建议先做溶剂阴性对照,确认溶解对动物无非特异性影响。
抑制剂是否可以高温灭菌?
大部分产品均通过化学方法合成,反应条件一般在 50-80℃ 之间,因此不建议使用高温灭菌法进行灭菌,建议用 0.22 μm 滤膜过滤灭菌。
产品溶解需要超声吗?如果没有超声仪怎么办?
超声可以加快粉末的溶解速度,如果您的化合物溶解不了,建议您尝试超声。如果您没有超声仪,建议您选择较低母液浓度,或者较少粉末量,尝试溶解。

缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris-HCl, 10% Sucrose, 3% Glycine, 100 mM NaCl, 0.1 mM EDTA, 0.05% Tween 80, pH 8.0.
复溶方法
Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储
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. Solutions are shipping with dry ice.
