Re: ORO
Hi Betsy,
When we do mouse aortas we dissect, bisect, and pin out on dental wax
before we do the ORO. The problem with ORO is that it "moves" around
if it is touched, squeezed, or pressed upon. It is better to have
them pinned out before staining. Then the staining is done in the
normal way, for example, by the Armed Forces Institute's protocol on
the "whole mounted" tissue.
We also normally do a Sudan IV instead of ORO. It is much more
stable and precise.
Take care,
Jo Dee Fish
