Ron -
I process strictly mouse tissue - my protocol is 45 min in each station, 2x
STF, 50% ETOH, 70% ETOH, 2x95% ETOH, 2x100% ETOH, 2x xylene, and 2x paraffin -
for a total of 9 hours.  I could probably go shorter, but this seems to work
well for all tissue types, even teensy adrenals.  If the tissue has been fixed
for 24-48 hours, I skip the STF (Strecks Tissue Fixative) and start off in
50%.
Good Luck.

Dear Ron

I am interested in your protocol but I do not know what "Strecks Tissue Fixative" is. Can you help me?
