Abstract
This protocol for H&E staining can be applied to either fixed or unfixed frozen cryosections.
Materials
1. Coplin jars
2. 95% Ethanol
3. Hematoxylin
4. Bluing Solution
5. Eosin
6. 100% Ethanol
7. Xylene
8. Coverslips
9. Cytoseal
Safety warnings
1.Safety glasses or goggles, proper gloves, and a lab coat required. The area should be adequately vented and a lab mat placed underneath all solutions.
2. Xylenes should be used in the fume hood.

Collect post-IMS autofluorescence
Remove matrix from tissue sections by incubating in 100% alcohol, dipping gently for 00:00:30 . Repeat this step 2-3 times until there is no visible matrix on the slides.

Dark purple nuclear staining and pink cytoplasmic staining allow the user to readily distinguish retinal layers such as (from bottom to top) the: sclera, choroid, retinal pigmented epithelium, photoreceptor layer, outer nuclear layer, outer plexiform layer, inner nuclear layer, inner plexiform layer, ganglion cell layer, and nerve fiber layer.
