I know a lady who did the Churukian Oil red O that was discussed last week
or so on cell cultures with excellent results (seen in Science magazine on
stem cell publications and advertisements in the past couple of years, her
work!)

It was less messy than a protocol with propylene glycol, easier to rinse
off excess stain from cell cultures, and stains beautifully with
hematoxylin counterstain with excellent brilliant red contrast to the blue
counterstain. 

Oil Red O can also be purchased in small quantities from Aldrich, sister
company to Sigma, and maybe a bit cheaper from Fisher or VWR if you have a
term contract agreement from these companies.
