Hi Sarah
 Actually, There is no micotmy involved. We biopsy the aorta. Clean the surrounding fat, cut it down the middle with a blade. And then we stain with Sudan 4. The aorta is mounted whole on a wax plate. we hydrate the tissue with PBS before we stain. This worked fine with the Sudan 4. Should I discontinue hydrating with PBS and use water instead with the Oil Red O.
Also with the Oil red O, we were rinsing them with isopranol before we stained them. Could this be the problem?

I remain yours truely,

I do oil red a lot.  You are doing it on frozen sections right?
What are you coverslipping with?
Need a few more details of the protocol and I might be able to help =)

Hi Histonetters
I am staining the plaques in aorta. I perfuse my animal with pbs before I biospy the aorta. I then pin the aorta down onto a wax plate and  then i stain the inside of the aorta for my plaques.
This seems to work well with the Sudan 4 but not so much with the Oil red o. The person who was doing the sudan 4 is no longer here and we have plenty of Oil red o. My thinking was that it should stain the same but I am not getting results with the Oil red o.
My question is what is the difference and what should I do differently with the Oil red o?
Thanks so much for your help!

I remain yours truely,
