[Histonet] IHC on H&E section

[Patsy Ruegg]

I know this has come up before but don't remember the details.  I would like
to do IHC for AE1/AE3 on a slide from a study set that has been H&E stained
and coverslipped for some time now.  Please advise.  Is there a preferred
method for removing the coverslip and maintaining the section integrety?
Destaining the H&E?  Doing the IHC stain on this section?
