Sulfobromophthalein (Bromosulfophthalein) disodium salt is an organic anion dye used in the study of a variety of membrane carriers expressed in animal tissues and involved in transport of agents and metabolites. It is a synthetic dye introduced in 1925 for assessing liver function and also acts as a pH indicator dye. It has been commonly used as both a substrate and inhibitor of organic anionic transporting polypeptide 1B1 (OATP1B1), OATP1B3, OATP1A2, OATP2B1, and MDR2. For research use only.
