RE: Oil Red O Question
|From:||"Molinari, Betsy" <BMolinari@heart.thi.tmc.edu>|
Another ORO question. A pathologist wants ORO on paraffin sections. I
have found one protocol for this method in the AFIP manual. Has anyone
had any experience with this? It calls for the slides to be
deparaffinized and hydrated to water,then placed in absolute propylene
glycol for 3-5 mins. then stained in a 0.5%ORO solution for 48-72 hours.
