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.
Other Notes:	Fluorescent thiol-specific reagent
Packaging:	Bottomless glass bottle. Contents are inside inserted fused cone.
