Ponceau S, BS

Description

Both Ponceau S and Ponceau BS are synthetic dyes commonly used in biological research. They are commonly used as protein stains to visualize proteins in western blots and other protein detection analyses. Ponceau S is a red dye, while Ponceau BS is a blue shade of the same dye. Both dyes bind to positively charged amino acid residues in proteins for easy visualization. However, Ponceau S is more commonly used due to its higher sensitivity.
