動物體內(nèi)配方計算器(澄清溶液)
第一步:請輸入基本實驗信息(考慮到實驗過程中的損耗,建議多配一只動物的藥量)
第二步:請輸入動物體內(nèi)配方組成(配方適用于不溶于水的藥物;不同批次藥物配方比例不同,請聯(lián)系Selleck為您提供正確的澄清溶液配方)
計算結(jié)果:
工作液濃度: mg/ml;
DMSO母液配制方法: mg 藥物溶于μL DMSO溶液(母液濃度mg/mL,注:如該濃度超過該批次藥物DMSO溶解度,請先聯(lián)系Selleck);
體內(nèi)配方配制方法:取μL DMSO母液,加入μL PEG300,混勻澄清后加入μL Tween 80,混勻澄清后加入μL ddH2O,混勻澄清。
體內(nèi)配方配制方法:取μL DMSO母液,加入μL Corn oil,混勻澄清。
注意:1. 首先保證母液是澄清的;
2.一定要按照順序依次將溶劑加入,進行下一步操作之前必須保證上一步操作得到的是澄清的溶液,可采用渦旋、超聲或水浴加熱等物理方法助溶。
