DCFH-DA and Fluo-4 AM Fluorescence Staining of Salidroside Treated MCF-7 Cells

Add 10 micromolar of Dcfh-DA fluorescence probe to MCF7 cells and incubate at 37 degrees Celsius for 20 minutes. After incubation, remove the excess Dcfh-DA by washing the cells three times with PBS. Next, test the fluorescence intensity using a fluorescence microscope and an excitation wavelength of 488 nanometers, and an emission wavelength of 525 nanometers.

Incubate the MC7 cells with a five micromolar Fluo-4 AM fluorescent probe solution for 45 minutes at 37 degrees Celsius. After washing the cells three times with PBS, determine the fluorescence intensity using a fluorescence microscope with excitation at 488 nanometers and emission at 516 nanometers. Salidroside significantly enhanced ROS fluorescence signals shown by Dcfh-DA immunofluorescent staining.

Consistently, Salidroside intervention also distinctly elevated calcium production, evidenced by Fluo-4 AM immunofluorescent staining.
