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;

2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;

3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);

4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
