Happy New Year everyone!
Can we start a discussion once again on what causes holes in nuclei? It is
pretty clear in my experience it has something to do with heating at least
for me with antigen retrieval. When I do HIER at ph 8 especially I am
seeing a lot of holes in nuclei. H&E on same tissue alone without HIER/IHC
doesn't seem to exhibit this artifact (holes in the nuclei). I bet it can
also happen if the tissue is not fixed well enough to protect it from
paraffin processing but right now I am seeing it more after HIER, don't see
it as much on my IHC slides with no AR or when I use eier instead of hier.
Also notice that ph6 HIER and Ph9 HIER are not as bad as when I use Ph8 for
the same times and temps.
