[Histonet] c-fos

[Turner, Scott]

Are you sure it's "thermosol" and not "thimerosal"?  Thimerosal is a commonly used preservative and can be found on the Sigma website (CAS Number: 54-64-8).  Thermosol is a process used in commercial dyeing.

I also confirm that fos IHC can be performed on frozen sections after 
fixation-cryoprotection without thermosol. If you really need a 
preservative you can use sodium diazide 
(http://www.sigmaaldrich.com/catalog/search/ProductDetail?ProdNo=71289&Brand=FLUKA).
