[Histonet] Quality of tissues: freeze - thaw - freeze

[Daniel Eberhard]

Dear Listers,
some month ago I prepared some mouse tissues for cryo-sectioning without 
fixing the tissues before.
Now I have found out that usual fixing of sections is not efficient for 
our purposes, and
whole mount fixation (e.g. with pFA) would have been much better.
Thus my question:
Have some of you ever thawed unfixed tissue blocks,
fixed the tissues and re-frozen them? I´m afraid the
integrity of the tissue might be spoiled and of course:
some of the tissues are valuable and unique.
Any hints are welcome
thanks
Daniel.
