Whether or not you pre-hyb in ISH may be based on the type of probe you are
using.  If you have a clean, specific probe you would not need to pre-hyb,
but if your probe is not very clean, or has a lot of repetitive sequence in
it, pre-hybing can "clean-up" your signal.
We generally pre-hyb our FISH probes 37 C for 30 min because they contain a
lot of repetitive sequence.  Pre-hybing gives us a better signal.

Hope that helps,
