1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
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。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
