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 Mrp2.3 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.

Route of Administration: Intravenous

In Vitro Use Guide

In competitive binding studies in vitro between Sulfobromophthalein (BSP) and a series of organic anions (sodium fluorescein, indocyanine green, bilirubin, sodium taurocholate, flavaspidic acid glucaminate, and iodipamide methylglucamine), the incubation mixture contained 500 ug of BSP and equimolar amounts of the aforementional organic anions. On the average, 160 +/- 2 ug BSP was bound per mg of membrane protein and 1.4 +/-0.1 ug BSP bound per unit of Co++-CMPase activity in 15 membrane isolates. BSP binding was maximal at 500 ug BSP/ml in the incubation mix with proportionately less binding observed at lower concentrations. BSP concentrations above 500 ug/ml reduced BSP binding and produced dissolution of cell membranes.
