[Histonet] Pre-cut controls

We precut our controls and place them in the refrigerator.  We do not dry
them until they are taken out for use.  The only issue we have found is with
Her-2-neu and what we do is only cut enough for 2 weeks use.

Does anyone know why IHC control slides cannot be cut ahead of time?  I've
done it at other facilities, but I have been told it is not permissible
here, without any explanation.  Any ideas? Also, has anyone ever heard of
refrigerating pre-cut IHC control slides?  One person suggested to me that
they stopped cutting them ahead of time because they were getting
condensation on them & the stains wouldn't work.  Then she informed me that
they were stored in the fridge.  Seems to me the condensation would have
formed upon removing the slides from a cold environment to a room temp. Your
thoughts/theories are appreciated. Fran Walker Histology Technical
