RE: tissue preservation
If I were doing this I think I would divide the lung sucrose protect and
freeze some, paraffin embed some and keep the blocks. If you really want to
keep some in solution I think I would use 70% ETOH.
Interested in knowing others opinions as well.

Subject: tissue preservation
I have whole lung tissue, from rat, obtained by perfusion with 4%
paraformaldehyde, removed, and then further fixed in PFA [that's
paraformaldehyde ;-) ] for 3 days. The plan is to collect thick vibratome
sections, so the tissue will never be embedded. I would like to keep part of
the lung for sectioning in the future and to carry out immunocytochemistry.
What solution should I keep them immersed in? Right now they are in PBS, at
4deg C but I feel that some preservative should be added to prevent
decomposition. However, keeping them in fixative may reduce their
I would appreciate hearing any suggestions from this very knowledgable
