[Histonet] long term storage of specimens

[Favara, Cynthia (NIH/NIAID)]

Janette,

A million years ago before the era of  litigation we used to take whole
organs and impregnate with paraffin. These were usually hearts with
malformations that had been sectioned to show the malformation. If you are
interested I can try to find more information.

Have you considered plastination?  The specimen is permanently inpregnated
with a plastic.  This removes the need for storing in any solution.
Try contacting Anatomical Pathology at the University of Queensland for more
details.  It has been done by Robbie Boyse on whole organs quite
successfully.

Histonetters,

I have been asked to post a question:

A museum has tissue samples for teaching stored in 10% formalin. They are
wondering what other solution they might be able to use that would be less
toxic. This would take the place of the formalin for long term storage. I
believe they take the samples out for demonstration so putting them in a
plastic is not an option.

Any suggestions????
