RE: Storage of frozen sections

From:Chris van der Loos

Hi,
Here are my cryostat-details:
After cutting the cryostat slides we let them dry overnight under a fan. 
There are stories here that longer drying will result into more crisper 
staining of membranous antigens than short drying. I have never checked this.
Next morning the slides are packed face-to-face (with little carton strips 
at the glass-ends) in Parafilm and put back into carton boxes the slides 
came in (Star Frost, coated). Six of those carton boxes can be stored in a 
plastic Roche storage box. The Roche boxes are placed in an aluminium tower 
in the -80°C freezer. We don't use any desiccants. As far as I know a 
temperature of -80°C guarantees a very dry environment!
After removal of slides from the freezer, we let them sit still packed 
under a fan for at least 10-15 min before unwrapping. Acetone-fixation is 
done right after unwrapping.
