Example protocol
PREPARATION OF STOCK SOLUTIONS
Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles
Add 13 µL of DMSO to the MitoROS™ 580 vial and mix well.
Note: Any unused stock solution can be stored at -20 °C, protected from light.
PREPARATION OF WORKING SOLUTION
Dilute the DMSO stock solution into Hanks solution with 20 mM Hepes buffer (HHBS) to make a 2X working solution.
Note: The 2X MitoROS™ 580 working solution is not stable, use it promptly.
SAMPLE EXPERIMENTAL PROTOCOL
This protocol is a mere guideline and should be optimized to suit your specific requirements. Prior to making the MitoROS™ 580 working solution, treat cells as desired.
Treat cells as desired.
Incubate the cells (such as 100 µL/well in 96-well plate) with equal volume of 2X MitoROS™ 580 working solution for 10-30 minutes at 37 °C, protected from light.
Note: The final in-cell concentration of the MitoROS™ 580 should not exceed 1X. Higher concentrations can lead to cytotoxic effects, such as altered mitochondrial morphology and fluorescence redistribution to nuclei and cytosol.
Note: Different cells react to MitoROS™ 580 differently, adjust the working concentration accordingly.
Wash cells gently three times and replace it with HHBS buffer.
Analyze the cells with a proper fluorescence instrument (e.g., a fluorescence microscope, flow cytometer) with Ex/Em = 510/580 nm.

HeLa cells were seeded at a density of 100,000 cells per well in 100 µL and incubated overnight in a 96-well plate with black walls and a clear bottom. For the AMA treatment group, cells were treated with 50 µM Antimycin A (AMA) at 37°C for 30 minutes, followed by incubation with MitoROS™ 580 for 1 hour. In the untreated control group, cells were incubated with MitoROS™ 580 at 37°C for 1 hour without any prior AMA treatment.

HeLa cells were seeded at a density of 100,000 cells per well in 100 µL of medium and incubated overnight in a 96-well plate with black walls and a clear bottom. The next day, the cells were treated with either 50 µM Pyocyanin (Pyo), 50 µM Antimycin A (AMA), or left untreated as a control. These treatments were applied at 37°C for 30 minutes. Following this, the cells were incubated with MitoROS™ 580 at 37°C for 1 hour.
