Application

Bromobimane is used for the determination of thiols by the HPLC method. It is suitable as a pre-column derivatization agent for fluorometric determination of 2,3-dimercaptopropane-1-sulfonic acid and other dithiols. Bromobimane has been used as a fluorescent label in studying oligomycin-sensitive ATPase from beef heart mitochondria.

Features and Benefits

The benefits of using Bromobimane for the analysis of low molecular weight thiols are: Highly selective. Rapid reactivity. Ease of separation of derivatives by reverse HPLC. Ability to penetrate cells.

General description

Bromobimane, also called probe for thiols, is a fluorescent reagent activated upon a photolysis reaction. Bromobimane in solution reacts with small thiol groups (e.g., GSH) and with reactive protein thiol groups (e.g., hemoglobin). The reaction of Bromobimane with thiols is of second-order and dependent on pH. And, upon reacting with thiolate, it activates the water-soluble fluorescent product for detection.
