- Lightly stain nuclei with Mayer’s Hematoxylin Solution for 1 minute.
- Rinse with tap water for 3 mins
- Mount with aqueous mounting medium.
Technical Points
- Include a positive control
- Cryostat sections 8 to 10 microns for formalin fixed smears. Formalin fixation gives good results.
- Step 9 – Obviously, the section must not be taken through clearing solvents prior to mounting, as this will remove the lipid to be detected.
