It depends on what you are using the oil red o for. Lipofuscin and ceroid can be demonstrated with an oil red o stain after processing. Jennifer MacDonald

Liver mistakenly processed in paraffin (had to be in OCT instead)! Sent by: histonet-boun...@lists.utsouthwestern.edu Hello Histonetters, First time writer, long time reader. I'm a newbie tech in academia and I was given a simple task which I think I pretty much screwed up. I should have embedded half of a mouse liver in paraffin for microtome sectioning while the other half should have been embedded in OCT for cryosectioning (for oil red o). I made the mistake last night of placing both liver halves into the tissue processor. The liver I intended for OCT embedding is now hard as wax. Is there any way to deparaffinize processed organs and may I embed them in OCT for proper cryosectioning? I imagine that the liver would get dehydrated, I would get crappy sections, and Oil Red O won't work. Any suggestions are welcome. Thank you so much, Zoe W. -- "It costs nothing to say something kind.
