Title: The best embedding medium for immunohistochemistry
Post by: bertie1 on February 04, 2005, 09:39:06 AM
Hi guys,

I have a quick question. I want to do immunohistochemistry on thin sections (2-10 micron) and want to know which medium is the best for the job. I really want to preserve as much of the cellular and even subcellular structure as possible and without much tissue shrinkage. I have been looking into methacrylates but there are so many that I'm unsure as to which would be the most suitable?

Are there any pitfalls with using methacrylates over paraffin? One of the advantages I can see with some methacrylates is that TEM is also possible. But I figure that removing the resin is not the nicest.

Thanks,

Bertie

Try glycolmethacrylate. Polysciences website has some very good descriptions of their different resin kits and the use of each.
Make sure your resin does not generate too much heat while polymerizing. This can destroy antigens.
Ultramicrotomes for sectioning are very expensive. Then you will need glass knives for thick sections. And a glass knife maker to make the knives, plus accessories to attach the little water baths to the knives.

Good luck.

I get great immunostaining on 4um paraffin sections with near perfect preservation of overall morpohology.
