Biological Activity: Ponceau S (Acid Red 112) is a non-specific protein dye commonly used as a stain for Western blot. Ponceau S is used in an acidic aqueous solution that is compatible with antibody-antigen binding and dyes the proteins on the membrane red[1][2][3].

Cat. No. Product Name Purity Description
HY-12489A Ponceau S, BS 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.
