Dihydrorhodamine 123 is an uncharged and nonfluorescent reactive oxygen species (ROS) indicator that can passively diffuse across membranes where it is oxidized to cationic rhodamine 123 which localizes in the mitochondria and exhibits green fluorescence.

Frequently asked questions (FAQs)

I am using the reactive oxygen species detection dye, Dihydrorhodamine 123, and when I put the dye in a solution of water and illuminate with UV light, I see a quick change in signal, even without cells. What is happening and how can I stop this?

You cannot stop it. Any time you illuminate a dye, including this one, photodegradation of the dye will lead to the production of singlet oxygen and free radicals. This in turn causes many ROS indicators, like this one, to become oxidized. If you are testing ROS using UV illumination, all you can do is use this as a baseline and subtract the signal from the sample with cells. The best you can do is reduce the illumination intensity (though this will also reduce the specific signal emission).
