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

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Reagent for labeling thiols in biol. materials

Storage Class
