常见问题解答
抑制剂能否用于动物实验?
可以的,我们的抑制剂都可以用于动物/体内实验。但有些化合物还没有用于动物实验的文献,这种情况下,建议您先做预实验,确保研究的可行性。
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。
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。
Tween-20 可以用 Tween-80 替代吗?
不建议使用 Tween-20。相较于 Tween-20,Tween-80 的耐受性更好,Tween-80已被用作评估实验药物和毒物的行为影响的工具,且没有明显的副作用。 参考文献:Castro CA, Hogan JB, Benson KA, Shehata CW, Landauer MR. Behavioral effects of vehicles: DMSO, ethanol, Tween-20, Tween-80, and emulphor-620. Pharmacol Biochem Behav. 1995 Apr;50(4):521-6.
化合物如何用于动物实验?如何确立剂量、给药方式等?
同一个化合物对不同动物模型、不同疾病模型的用法不一样,建议根据实验目的,查询文献选择用法。 常见的给药方式包括腹腔注射、灌胃等。由于首过效应,一般可以灌胃的也可以腹腔注射,可以腹腔注射的不一定适合灌胃。不同种属的给药剂量可以根据官网的表格换算。但仅供参考,实际应用中可能未必合适或者准确,尽量以具体某种动物给药剂量的参考文献为主。 我们的化合物都可以进行细胞动物实验,但有些化合物还没有用于动物实验的文献,这种情况下,您可以尝试进行动物实验,但我们无法提供使用方式,也无法保证药效。

分子量26.5 kDa (predicted). Due to glycosylation, the protein migrates to 28-40 kDa based on Tris-Bis PAGE result.
内毒素< 1 EU/μg by the LAL method.
缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
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
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
Glycoprotein A33 (GPA33) is also known as Cell surface A33 antigen, is a single-pass type I membrane protein which is expressed in normal gastrointestinal epithelium and in 95% of colon cancers. GPA33 The predicted mature protein has a 213-amino acid extracellular region, a single transmembrane domain, and a 62-amino acid intracellular tail. The sequence of the extracellular region contains 1 Ig-like C2-type (immunoglobulin-like) domain and 1 Ig-like V-type (immunoglobulin-like) domain characteristic of the CD2 subgroup of the immunoglobulin (Ig) superfamily, which contains. GPA33 may play a role in cell-cell recognition and signaling.
