Materials

• xylene
• 100% Ethanol
• 70% Ethanol
• H2O
• Mayer's Hematoxylin
• 1% Eosin Y (in water)
• 95% Ethanol

Protocol

• Removing Wax and Rehydrating

1. Place slide on edge and bake for 15 min at 60 degree C to melt wax
2. Deparaffinize and rehydrate sections
   1. Immerse for 5 min with agitation in xylene
   2. Immerse for 5 min with agitation in 100% ethanol
   3. Immerse for 5 min with agitation in 70% ethanol
   4. Place slide(s) in appropriate buffer (For H&E, use H2O) for 1 min

• H&E staining

1. Dip slide into Mayer's Hematoxylin and agitate for 30 sec
2. Rinse slide in H2O for 1 minute
   1. depending on the intensity desired, repeat this step if necessary
3. Dip slide in 1% eosin Y fo 10-30 sec with agitation
4. Wash twice with fresh xylene for 30 seconds.
5. Let slide dry.
6. Place 1-2 drops of mounting medium on slide and place coverslip over
7. Seal coverslip with sealant(nailpolish)

Notes

• Be sure to shake Eosin prior to placing slide in for staining because it will settle.
• The staining will get more intense after time, be sure not to oversaturate section

• Protocol take from summary of CSH Protocols; 2008; doi:10.1101/pdb.prot4987 and CSH Protocols; 2008; doi:10.1101/pdb.prot4986
