DETAILS

Description (English)

Biochem/physiol Actions
Monobromobimanes are essentially nonfluorescent until conjugated and readily react with low molecular weight thiols. Unlike common monobromobimanes, this carries a positive charge, thus permitting separation of conjugates by electrophoresis or cation-exchange chromatography
Other Notes
Reagent for labeling thiols in biol. materials1,2
