MitoDNA™ Blue 470
Example protocol
AT A GLANCE
Before using MitoDNA™ Blue 470 for the first time, allow it to thaw at room temperature. Then, briefly centrifuge it to collect the dried pellet.
Prepare cells in a growth medium.
Stain cells with MitoDNA™ Blue 470 working solution.
Incubate samples for 5 to 15 minutes at 37 °C.
Use a fluorescence microscope with a DAPI filter set to monitor fluorescence intensity.
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
Prepare a 5 to 10 mM MitoDNA™ Blue 470 stock solution in DMSO. For example, add 150 μL of DMSO to the MitoDNA™ Blue 470 vial to create a 10 mM stock solution.
Note: Prepare a single aliquot of the unused MitoDNA™ Blue 470 stock solution and store it at ≤ -20 º C, protected from light. Avoid repeated freeze-thaw cycles.
PREPARATION OF WORKING SOLUTION
Prepare a 5 to 10 μM working solution by diluting the MitoDNA™ Blue 470 stock solution in Hanks' solution with 20 mM HEPES buffer (HHBS).
Note: For optimal results, use this solution within a few hours of preparation.
Note: Cover the working solution with foil or store it in a dark place to protect it from light.
SAMPLE EXPERIMENTAL PROTOCOL
Plate the cells in a 96-well plate with black walls and a clear bottom.
Remove the cell culture medium and add 100 µL of MitoDNA™ Blue 470 working solution directly to the cells.
Incubate the cells at 37°C for 5-15 minutes, protected from light.
Note: The concentration and incubation time of MitoDNA™ Blue 470 may vary depending on the cell line. Test different concentrations to determine the optimal dose.
Remove the dye working solution and wash the cells twice with HHBS buffer.
Add HHBS buffer and analyze the cells using a fluorescence microscope equipped with a DAPI filter set.
