I know of no one who has success with ground sections, etched and
immunostaining. 

Methylmethacrylate must be totally removed from tissues for
immunohistochemistry.  Tissue in PMMA should be sectioned on a microtome
sections, then remove PMMA from sections using warm xylene, proceed with
staining.  There has been much discussion on this, so check out Histonet
Archives, look for Neil Hand - he is a wizard at IHC/PMMA embedded tissues,
with plastic removed and has had many publications on this.

I've already tried this a few times, but when I try to remove the
PMMA-resin the slices come loose. Normally I use a UV-curing glue for
fixing the slices onto the glass, but then I can only perform a
surfacestain on the slices (after a brief resin-removal).

jus a bit. Recently I had one succesfull effort (just one) with
silane-treated slide together with Loctite 401 superglue. The result was a
fine HE-stained slice, but when I tried to do immunology on another slide
the result where as usual (wich means bad).
