I can't speak to all of the stains mentioned, but I can say that H&E,
Masson's, PAS and methyl green-pyronin all work on JB4/gma sections at 1 to
5 microns.  There are some caveats.  First, the staining is much lighter for
thinner sections (go fig :-)).......

One reason the staining is much lighter in GMA than in paraffin is that the
sections are thinner, therefore there is less tissue to pick up the stains.
