在T细胞中，亲环蛋白和环孢菌素A可以结合[1]。通过产生亲环蛋白-环孢菌素 A 复合物，环孢菌素 A 抑制钙调神经磷酸酶 [2]。环孢菌素 A 抑制活化细胞中的钙调神经磷酸酶，IC50 值为 7 nM [3]。环孢素 A 阻止 NF-AT 移动至细胞核 [4]。环孢菌素 A 抑制线粒体 MTP 打开，IC50 为 39 nM [5]。

当小鼠、大鼠和豚鼠胃肠外或口服给药时，环孢菌素 A 会发挥免疫抑制作用 [6]。在器官移植中，可以给予环孢素A来阻止器官排斥[7]。

2%DMSO+30%PEG 300+5%Tween 80+ddH2O: 5mg/mL

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
7、 以上所有助溶剂都可在 Invivochem.cn网站购买。
