Room temperature storage has always worked fine for us, of course it all depends on the quality of fixation and processing, and what antigen you are after..........

We have done a study(Berez et.al in process) and slides stored in this fashion for 5 years stain better than freshly cut slides from the same blocks that have been stored at room temperature.

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).

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!
