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-s |
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. |
