I'm a college student doing a research project on the histology of the garter snake digestive tract and associated glands.  I already have tissues embedded in plastic, but all the books I can find have staining procedures for paraffin.  Does anyone know the staining procedures for plastic-embedded tissues?  The stains I'm hoping to use include Mallory-Heidenhain's azan, Best's carmine, Gomori's chrome alum hematoxylin-phloxine, Iron-hematoxylin and thiazine red staining, Bielschowsky-Foot's method, and Masson's stain, but methods for any stains that would be good for digestive tract and associated organs would be much appreciated!!!
Thanks,
