Sheila, You can't normally use osmium lipid fixation for paraffin sections because the lipid you want to see will usually have been dissolved out by the paraffin processing. You need to either post-fix in osmium (after formalin) before paraffin processing or use frozen sections. As mentioned, on

Osmium tetroxide solutions will fix your skin on contact, but skin grows back. Osmium tetroxide fumes will fix your corneas which are irreplaceable. Osmium tetroxide is dangerous, but it is manageable. First, make sure your fume hood draws really, really well. Put 100 ml of pH 7.2 phosphate-

For this difficult tissue, and for any other for that matter, add to your regular round water bath at 45ºC, 2 mL of liquid dish washer soap. The soap will reduce the surface tension of the water and will allow the sections to extend completely, eliminating any folds. René J. __

Osmium tetroxide is one of the most dangerous substances you can use in the laboratory. Your pathologist probably read some article or found an old photo of fat "stained" with osmium tetroxide and now wants you to do the same thing. The problem is that the fat is allowed to react to the fumes of
