I've also been using Amido black die to stain the membranes after blotting.
Same procedure as for Ponceau (0.1% dye in 1% acetic acid). Amido black is
almost the same sensitive as Coomassie, whereas Ponceau is much less
sensitive (moreover, blue stains are better viewable and easier to make a
good photocopy than red).
