实验计算
动物体内配方计算器（澄清溶液）
第一步：请输入基本实验信息（考虑到实验过程中的损耗，建议多配一只动物的药量）
第二步：请输入动物体内配方组成（配方适用于不溶于水的药物；不同批次药物配方比例不同，请联系Selleck为您提供正确的澄清溶液配方）
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，注：如该浓度超过该批次药物DMSO溶解度，请先联系Selleck）；
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。
体内配方配制方法：取μL DMSO母液，加入μL Corn oil，混匀澄清。
注意：1. 首先保证母液是澄清的；
2.一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
