Beschreibung

General description

Bromobimane is also known as monobromobimane. It is also a known probe for thiols and is a fluorescent reagent activated upon a photolysis reaction.

Application

Fluoreszenzfarbstoff für Thiole

Biochem/physiol Actions

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.
