[Histonet] CNS Fixation

[Kathleen Roberts]

Sara-

Welcome back!  We use 10% NBF also to fix our mouse & rat brains and 
spinal cords, and I use Ultrastick slides for sectioning (6 um sections 
are standard here, that's what my boss likes). I bake them in a 60 
degrees C oven for 30 minutes-overnight (depending on my schedule).   
It's rare that I have tissue come off the Ultrastick slides during 
staining...but then I stain my slides manually since we don't have an 
autostainer yet.

Good luck,
