Cell permeant reagent Dihydrorhodamine 123 (DHR 123) is a fluorogenic dye that is useful for the detection of reactive oxygen species (ROS) such as peroxide and peroxynitrite. ... to oxidize DHR 123 to its fluorescent derivative Rhodamine 123. Rhodamine 123 can be detected by fluorimeter, flow WebThe aim of this study was to assess the potential of dihydrorhodamine 123 (DHR123) to measure oxidative stress produced by human spermatozoa. The results were compared with 2', 7'-dichlorodihydrofluorescein diacetate (DCFH-DA) that is routinely used for assessment of H 2 O 2 produced by spermatozoa.
WebDHR-123 is a ROS-sensitive dye that easily enters a cell with lipophilic property, localizes to the mitochondria, and oxidizes to the highly stable, fluorescent derivative rhodamine-123 by mitochondrial ROS ( Sakurada et al., 1992; Ranganathan et al., 2009 ).
