[Histonet] Storing frozen rat brain slices

[Charles Scouten]

Even -80 is not cold enough, but the colder the better.  The ice will
gradually restructure as crystalline ice, and expand.  This will break
cell membranes and disrupt the tissue quality. Use as early as possible.

Question: I was wondering if anyone could let me know what is the
optimal storage for frozen rat brain slices (approx 2mm thick) which are
in OCT: -20 degrees celsius or -80?
Thanks in advance,
Emily
