[Histonet] Pre-cut controls

[Richard Cartun]

We pre-cut all of our control tissue slides and store them at RT.  We
cut tonsil every week.  Most others are used up in a month's time, but
some do sit for a year or longer.  Obviously, every laboratory is
different, but you should do a study to determine how long your control
slides remain reactive.

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.
