Cell experiment: |
MCF7 cells (2-3×105) are seeded in a 35-mm glass bottom dish before the experiment. Prior to imaging, cells are washed with 1 mL PBS, then incubated in 1 mL Hanks’ Balanced Salt solution (HBSS(+) without phenol red) containing 1 μM Fluorescein diacetate (0.1% DMSO as a cosolvent) for 5 min at 37°C. Cells are washed twice with 1 mL PBS and 1 mL HBSS is added before imaging. Fluorescence images of fluorescein and DsRed-Express2 were acquired in the FITC channel (excitation at 473 nm) and the DsRed channel (excitation 559 nm). The 16-bit images obtained are analysed[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。
