RE: Nuclear pallor

From:"Jones, Sarah - RAS"

I took a QA class at the NSH this year, and in this class Peter Jackson and
David Blythe of the UK talked about "Nuclear Meltdown".  We were told that
doing heat induced epitope retrieval with buffer or even with water would
reverse this effect.  You cannot reverse the effect of "Nuclear Bubbling
Artifact" this same way, however.  It's worth a try!  Good luck!

Hi histonetters,

Our lab is having a problem. Our doctors have been noticing that the H&E 
stain slides of some of the GI biopsies have uneven (poor) nuclear staining.

We use a closed processing system and we clear with xylene. I have not
any condensation nor contamination on the inside of the lid nor the
I can not figure out what is going on. I have attached, with compliments of
pathologist, a H&E slide.
It has only been notice with GI's and not with any other specimen.
Any suggestions will be greatly appreciated.
