One of the reasons that H&E slides fade is leaving them out in the light. Both fluorescent (some of the lights here are on 24/7) and natural light fade slides to some extent.

Subject: [Histonet] eosin fading

Hi all,
Would like an opinion on what causes eosin to fade while we are on the
fading of hematoxylin debate.  I find that when I stain a batch of
slides 6 months to a year later some of these slides are a lot paler as
regards eosin. I then restain and the slide is fine again. I use a
eosin/phloxine mixture.  Would using an alcoholic eosin mixture improve
this? I am using entellan as mounting medium.
