[Histonet] Hematoxylin issue

[SimmsColon, Janine]

Good afternoon all, 

 

I have been addressed with an issue which I would like some assistance
with. My pathologist recently reviewed some skin slides from 2007 and
noticed the hematoxylin was completely gone and only the eosin remained.
We use Gill's II hematoxylin, and glass cover slips with xylene
substitute mountant. The concern is that since we must retain slides for
10 years and the stain has "washed out" after only 5 this could be a
pretty big problem. I do not believe this particular lab has experienced
this problem before but I have only worked here for less than one year.
We stain in hematoxylin for 3 minutes, use commercially available
clarifier and bluing solution, each for one minute as well as one minute
tap water rinses in between and dip in 95% alcohol before and after a 1%
alcoholic eosin y solution. I searched the histonet archives for this
problem as well which is why I am mentioning the staining process but I
was curious if anyone out there had any suggestions or advice to avoid
this issue for future slides. Thank you in advance.
