If it was me, I would keep them as wax-embedded sections on slides,
with dessicant, at room temperature. They keep for a while, probably
You can also do the prehybridisation (i.e. rehydrate, fix, acetylate(?)
and dehydrate back through ethanol series, then store frozen at -70)
Try and use them within a month. This is only recommended for 35S
in situ. I wouldn't dehydrate a section that is to be DIG probed -
there is no need and you reduce the signal.
Hope this helps, and good luck.
