RE: [Histonet] IHC on H&E section


A variation on this theme is using a cigarrette lighter to "melt" the mountant and then pop-off the coverslip with a razor blade.  It takes about a minute per slide.  Good luck,
p.s. You can usually see an air bubble form under the coverslip when is ready to be popped-off.

	When working with a large tumor registry, I was asked to do IHC on many
	archived H & E slides.  To remove the coverslip, I placed the slide on a
	hot plate until the adhesive softened and then popped off the coverslip
	by slipping a razor blade under one corner.  No tissue was ever lost.
	While the slide was still slightly warm, I put it into xylene to remove
	the remaining adhesive. Then I continued down a typical decerating line
	to 70% ethanol which removed most of the eosin.  To remove the
	hematoxylin, I used periodic acid solution(I don't remember the
	concentration or time but I think it was similar to the PAS treatment).
	The pathologist was found that the IHC's on the archived slides where
	much more brilliant than on freshly cut sections.

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