CAS: 81-11-8

4,4'-Diaminostilbene-2,2'-disulfonic acid (DAIDS) is a fluorescent dye that can be used to measure the activity of mitochondrial enzymes. It is a substrate for polymerase chain reaction and can be used as a cell viability assay. DAIDS has been shown to cause mitochondrial membrane depolarization and cytosolic calcium release in prostate cancer cells. This compound also inhibits the proliferation of human liver cells and has been proposed as a potential analytical method for wastewater samples. The anhydrous sodium form of DAIDS has been shown to increase the rate of metabolism by up to 30% in rats with body mass index greater than 25 kg/m^2.
