suitable for fluorescence |
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. materials |
Packaging: |
Bottomless glass bottle. Contents are inside inserted fused cone. |
