[求助] DCFH-DA体外测材料ROS问题 已有1人参与

求助各位大神,有没有用DCFH-DA测体外ROS的,就是材料表面的,不加细胞,是应该怎么操作?是不是要将DCFH-DA先变成DCFH,如果是的话,加什么东西可以?

2.6. Chemical ROS assay
To study the insonation induced ROS generation in solution, RB4
was tested using a modified 2′, 7′–dichlorofluorescin diacetate (DCFH
DA) assay. DCFH-DA (1 ml, 1 mM in MeOH, Aldrich) was hydrolyzed in
NaOH aqueous solution (0.01 N, 4 ml) at RT for 30 min to yield a non
fluorescent DCFH intermediate. The solution was neutralized with
20 ml of NaH2PO4 (25 mM) and shielded with aluminum foil. The final
solution of DCFH was around 40 μM. RB4 (1.0 mg) was dissolved in
DMSO (1 ml), and then diluted with water into a 20 μM solution. The
RB4 solution (20 μM, 10 ml) was mixed with a DCFH solution (40 μM,
10 ml) as the test solution. The test solution (0.5 ml) was placed into
each well of a 24-well plate. The DCFH solution without RB4 was
included as a background control. The plates were treated with
ultrasound (0.4–1.2 watt/cm2) one well by one well for 30 s; the
insonated wells were then checked using a fluorescence plate reader,
ex 485 nm/em 520 nm.

我正好看见有一篇关于体外测定ROS,分享一下不知道对你有没有用。
