Permenant mounting of AP-NBT/BCIP slides

[Wes Garrett]

When using non-radioactive ISH with alkaline phosphatase and NBT/BCIP
chromogen, how do you permenantly mount the slides.  This chromogen is
soluable in solvents, and I have had no luck with either alcohol
dehydration, or clearing in xylene.  I have been told that this works,
but I either lose signal, or develop crystals where the precipitate
forms.

thanks
