Dihydrorhodamine 6G (DHR 6G) is the reduced form of Rhodamine 6G, which is used as fluorescent mitochondrial dye. It is nonfluorescent, but it readily enters most of the cells and is oxidized by oxidative species or by cellular redox systems to the fluorescent rhodamine 6G that accumulates in mitochondrial membranes. Dihydrorhodamine 6G is useful for detecting reactive oxygen species (ROS) including superoxide.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
