[Histonet] unstained paraffin tissue slides storage

Plain slide boxes is ok.  I think you can store them for up to a year in
a fridg. (4 degrees), but I usually pu them in a freezer (-20).

Hello,
I found here a few disscussions regarding the storage of tissue slides
but I did 
not find a clear answer to the questions I have. I would really
appreciate an 
answer from anybody that has experience with this.

I need to store for long term a bunch of unstained tissue slides for the
purpose 
of doing immunostaining even in a few years from now on. Unfortunatelly
they 
were stored for about 3 years at room temperature. What it is 
usually recomended: to store them at -20 degrees Celsius? If yes, is it
OK to 
store them in the regular 100 slides boxes? And when you need to start
an 
immunostaining just take them out of the freezer and let them at room
temp for a 
while before starting the stain or what procedure do you use?

I heard some labs keep them in nitrogen gas containers. Do you have any
info 
about this?

Any imput is appreciated!
Thanks!
