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].
In Vitro:Concentration of Ponceau S (0.001-2 (w/v); 5-10 min), acid concentration and acid type (acetic acid, trichloroacetic acid/sulfosalicylic acid) doesn’t affect the sensitivity of protein detection[1].
