Hi Terry & HistoNetters
I have done lots of successful large organ
stabilization in saline at 65°C for 20-35 minutes
(depending on the size of the organ. However, it
is important to emphasize that the purpose of
this step usually is to firm up the tissue so
that it can be subsequently cut up into thinner
pieces for processing, which must include a
fixation step, either in the microwave or on a
conventional processor, in formalin or some
non-formalin fixative. The saline will not work
alone as a fixation step, except in the case of
very small biopsies (as written up in an article
by Tony Leong)- a procedure I have not tried
myself.
best regards,
