Acid red 52

Sulforhodamine B can be used as a protein tag - by sulfamido condensation with a proteinaceous substrate containing a primary amine function. Sulforhodamine B will fluoresce red. Because of its red fluorescence it can be used in conjuction with fluorescein isothiocyanate (which fluoresces yellowish-green).


Soluble in water (20 mg/ml) or ethanol (5 mg/ml). Creates a bluish-red solution with a yellow fluorescence.
