Description

Protein stain for electrophoresis

Ponceau S dye is used to make a stain for rapid reversible staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. It is also suitable for electrophoresis, azo dye for reversible protein staining. This stain can also be used as a fiducial marker in mass spectrometric imaging.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
