Application notes

Hematoxylin staining protocol for paraffin embedded sections

 

  1. Incubate paraffin embedded sections in histoclear for 20 minutes
  2. Incubate slides in 100% ethanol for 3 minutes
  3. Incubate slides in 90% ethanol for 3 minutes
  4. Incubate slides in 70% ethanol for 3 minutes
  5. Rinse in tap water
  6. Incubate in hematoxylin solution for 5 minutes
  7. Rinse in running tap water for 5 minutes
  8. Dip in acid alcohol (8-12 fast dips)
    1. Recipe: 70% ethanol with 25mM HCl
  9. Incubate slides in tap water for 2 minutes
  10. Incubate slides in Scott's water for 2 minutes
    1. Recipe: 10g/l MgSO4, 0.66g/l NaHCO3
  11. Dip and swish in 70% ethanol
  12. Dip and swish in 90% ethanol
  13. Incubate slides in 100% ethanol for 3 minutes
  14. Incubate slides in three changes of xylene for 1 minute per incubation
    1. Carry out in a fume hood as xylene is extremely toxic
  15. Mount with DPX and leave to dry in a fume hood overnight before imaging
