RE: [Histonet] brain tissue

From:"Charles Scouten"

May I ask, are the brains perfused or immersed?  Perfusion gives better tissue quality, since the whole brain is a big chunck for immersion. Interior poorly fixed is one interpretation of the brittle problem.  

I have not used paraffin, can cannot speak to the inclusion problem.  Why not freeze the brain and cut whole sections?

Dear Histonetters
I work with rat´s brains fixed in paraformaldehyde. I have problems with paraffin inclusion and section. I always obtain brittle sections.
