I forgot to mention that we tried a pretreatment technique for ISH
published in JHC (don't remember the ref though) which called on a
microwave treatment instead of proteinase K treatment. This technique did
not improe our ISH signals but did clearly cause non-spcific binding of all
of our probes to the tissue, and this whether used on paraffin, PEG or
