Ponceaus S Staining Solution is a ready-to-use membrane stain for evaluating the transfer efficiency of a western blot. This stain is compatible with nitrocellulose and PVDF membranes. Ponceau S staining is reversible and can be removed with a short incubation in 0.1% NaOH.

Features include:
• A nondestructive, reversible method to stain and detect proteins on nitrocellulose and PVDF membranes
• Minimal nonspecific interactions with the membrane surface; provides a reliable method for visualization of protein transfer to a membrane
• Simple and quick staining protocol that results in reddish-pink bands that are easily photographed
• Reversed easily in less than five minutes
• Subsequent western blot detection unaffected as the stain does not alter the membrane-bound protein
