I have not actually done the stain, I dissect and pin out the aortas (100's
of them!) and the investigators do the staining and imaging. The paper you
referenced was actually edited by our institute President. The protocol we
-Place pinned out aortas in 70% EtOH for 5 minutes.
-Stain in 0.5% Sudan IV in 1:1 acetone:absolute EtOH.
-Differentiate in 80% EtOH for 3 minutes.
-Rinse in tap water for 1-2 minutes.
-Store in 3% paraformaldehyde in PBS at 4C until imaging can be done.
I also googled Sudan IV stain and found a very similar protocol right away
at the whitewolf.newcastle.edu.au website, and I'm sure there are others out

Subject: [Histonet] Sudan IV staining
A researcher at an area hospital has asked for some help performing Sudan IV
staining of rat aortas. She would like to look for atherosclerotic lesions
by en face analysis. I am not familiar with this. I have reviewed the
paper she is using as a reference and it does not go into detail about the
staining protocol for this. The journal article is entitled " Synthetic LXR
ligand inhibits the development of atherosclerosis in mice
Is there anyone on the histonet who performs en face analysis and can help?
