RE: Oil Red O

From:"Gutierrez, Juan"

The way I've done it is:
1. Rinse tissue in running water for a few hours to get rid of formalin.
2. Pat dry, and freeze as you would any other tissue.
3. Cut sections at anywhere between 4-8 microns.
4. Place slides in absolut Propylene Glycol for 5 min.
5. Transfer slides to Oil Red O for 2-4 hours.
6. Rinse in 85% propylene glycol for 5 min.
7. Counterstain with hematoxylin.
8. Rinse air dry and coverslip with aqueous media.

Hope this helps,

Hi Everyone!

I was hoping to get a protocol for Oil Red O  on NBF fixed frozen mouse
and intestine.  I would appreciate a freezing protocol as well.   We are
a debate in our lab as to the best way to approach this.  Thanks in advance
the help!
