实验操作小课堂
常见问题解答
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。
如何选择合适的溶剂?
常用的溶剂包括DMSO、水、乙醇等。建议您根据抑制剂给出的溶解度参考,选择合适的溶剂。如果该抑制剂可以溶于DMSO,建议使用没有吸潮新开封的 DMSO,如果有潮气污染,很容易带来抑制剂降解或难溶的问题。如果该抑制剂可以溶于水,建议您根据实验类型选择无菌水、生理盐水、无菌 PBS 、培养基等作为溶剂。
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。
抑制剂产品应如何储存?
粉末储存在 -20℃,可以存 3 年以上。 母液一般储存于 -80℃,可以存 1 年以上,建议多分装几管,避免反复冻融。 常用的存于 4℃,可放一周以上。
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 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.
研究背景
IL-22R belongs to the type II cytokine receptor family. It contains 2 fibronectin type-III domains and is expressed in the colon, liver, lung, pancreas, and kidney. IL-22R also can be expressed in keratinocytes of normal skin as well as in psoriatic skin lesions. Overexpression of IL-22R can be detected in synovial fluid cells from rheumatoid arthritis and spondyloarthropathy patients. IL-22R is a component of the receptor for IL20, IL22, and IL24. The component of IL-22R formed by IL22RA1 and IL10RB enables IL22 signaling via JAK/STAT pathways. IL22 also induces activation of MAPK1/MAPK3 and Akt kinases pathways. Component of one of the receptors for IL20 and IL24 formed by IL22RA1 and IL20RB also signaling through STATs activation. IL-22R mediates IL24 antiangiogenic activity as well as IL24 inhibitory effect on endothelial cell tube formation and differentiation.
