    Definately, use Eosin. It is simple and already in abundance in most labs.
We have been using it recently and what a difference. Not only are embedders
less likely to miss one of our prostate biopsies, but the cutters can see the
tissues better so they are less apt to face through the block. Putting a couple
hundred ml in the 80% (or 70%) should be sufficient and the stain in the tissue
is removed during rehydration after being cut. So it doesn't interfere with
specials or IHC.
