RE: [Histonet] testicles

From:"Alan Bright"

Dear Inga,

On our cryostats I would have the specimen temperature set @ -12C and the microtome chamber temperature set @ -20C as this will stop any adherence to the knife and anti-roll plate. You are much too cold at present on the specimen temperature. 
I see you are a neuro lab these settings would be fine for brain too.

Best Regards

Hi everyone,

A collegue of mine is trying to section frozen rat testicle (perfused 
and cryoprotected in sucrose) at -30C. Is that a good temperature to 
use? The sections seem fragile and tend to break. Theyre 10 microns 
thick. Or is it bad fixation?

Thanks in advance for any help!

Inga
