Dear fellow histonetters:

We know that ER/PR control slides should be stored in some form of a 
desiccator where the slides are subject to low humidity.  This storage 
requirement is used to facilitate antigenicity.  Are there any other IHC 
control slides that should be stored in this fashion or by any other method?

Our lab is located in a very humid area.  What is your area's average
humidity?

Any input would be appreciated.  Please respond via histonet or privately, 
if you would like.

Thanks in advance,
