Uses activates heme oxygenase, anti-oxidative stress, inhibits DNA fragmentation A red coloring medium made from phenol or carbolic acid. It is soluble in alcohol and ether but insoluble in water. When fabrics were steeped in this solution, the color was nonactinic and therefore safe for darkrooms, windows, and doorways. Aurin was also mixed with water-soluble gums and brushed on the backs of collodion and silver bromide gelatin plates as an antihalation layer. Rosolic acid is used as a pH indicator in the range from 5.0 to 6.8. It acts as an intermediate in the manufacturing dyes. It is involved in the activation of heme oxygenase and in the inhibition of DNA fragmentation. It finds application in the selective isolation of coliform bacteria.
