Ponceau S is not recommended for gel staining; it is advised only for use with membranes. Using Ponceau S in acetic acid may precipitate and fix the proteins in the gel, which is not advisable if a protein transfer to a membrane is planned for a western blot.

Is it practical to stain protein gels directly with Ponceau S without transferring to membranes in order to assess the amount of protein and number of bands in a protein sample? Is there a direct gel staining protocol available for this purpose?
