RE: [Histonet] Frozen sections

From:"Stapf, Ross"

I suspect that if it stays frozen it will be fine.  The problem with
leaving it in the cryostat is the defrost cycle.  So it isn't staying
frozen.  I think it would be best kept in a -70 freezer.

I will be interested to see other opinions.

Subject: [Histonet] Frozen sections

  I was wondering about a policy for the length of time a frozen section
block can safely remain in a cryostat before it is taken out and
routinely processed.  I have a pathologist that wants to leave the
frozen tissue block in the cryostat for up to 3 days in case he wants to
do immuno stains from it.  I would be interested to here of other
policys from other institutions regarding this issue.

Thank you,
