HEK293 cells transiently transfected with HARS-expressing plasmids were harvested and lysed in CelLytic M buffer containing mammalian protease inhibitor cocktail for 20 min at 4 °C. FLAG-tagged HARS is purified by binding to an anti-DYDDDDK resin per manufacturer protocol and eluted by competition with 3X-DYKDDDDK peptide in buffer containing 50 mM Tris-HCl pH 7.4, and 150 mM NaCl (purification of human HARS)[2].

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,
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 saline,混匀澄清。
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。
