For perfused brain, as soon as you pick up the section, place your 
finger under the section for just a second, and then air-dry the slides 
at room temp. We like charged slides. I store them in a slide box with 
some desicant in the -70 , if fresh frozen. Once they are fixed, or if 
they are perfused, I store them in the 4 degree fridge.
