Sulfobromophthalein Sodium Salt

Sulfobromophthalein (BSP) is a dye with a high affinity for organic anion transporting polypeptides (OATPs) and has been used as a substrate for multidrug resistance associated protein 2 (Mrp2). BSP is transported into hepatocytes by OATPs and, after conjugation to glutathione, is excreted into bile by Mrp2. It was found to inhibit the aldo-keto reductase ARK1C20.
Sulfobromophthalein (BSP) is used in diagnosis of hepatic disorders. It is also used for the quantitative determination of proteins.
