Whoa there, Ken! You are about to shoot yourself in the foot! More or less
by definition, there are no lipids left in paraffin sections because they
have been processed through graded alcohols and xylene before paraffin
impregnation. Real cowboys do their lipid stains on air-dried frozen
sections. Sudan Black and Oil Red O are personal faves. Good luck!
