storage of tissues
I have a question about storage of tissue that I hope someone can help me
with. Does anyone know how long animal tissues can be stored in 70% ethanol
without any damaging effects or hardening of tissues (after they've been
We normally don't keep our tissues in 70% ethanol any longer than a few
weeks, but we've been told we need to keep all of our formalin under a fume
hood, (even if they're in closed containers) which we have very limited
space for. These are tissues that we want to keep long term; we dispose of
unwanted tissue 30 days after we receive them. If we could store them in
ethanol, this would solve our problem.
Thanks for all of your help in advance.
