I store all cut paraffin sections for IHC control at 4dc and without heating
to melt the paraffin, even with that I have seen some loss of antigenicity
over long periods of time for certain antibodies.

Subject: [Histonet] Control slide storage

The issue was brought up in the lab regarding the storing of IHC control 
slides. What experience has anyone had on the effects of long term storage 
and staining quality. We store the slides non preheated (with the paraffin 
still on them).
