Ponceau S Staining Solution

Ponceau S Staining Solution: Ponceau S Staining Solution, as a reversible stain method ,is used to stain electroblotted proteins on blot transfer membranes. Transferred proteins (>100 ng/band) appear as red bands on a white background,proteins are stained by the Ponceau S Staining Solution after electroblotting from one-dimensional or two-dimensional polyacrylamide gels to blot membranes such as polyvinylidene difluoride (PVDF), nitrocellulose membranes, but is not sutiable for nylon membrane because of negative charge of Ponceau S . The solution is provided as a 5x Strength solution .
