gel chemistry

From:Gina Clarke


Does anyone know of any recipes for a gel which _can_
withstand the rigors of paraffin processing (chemicals,

The gel is used to cure into a supporting block for
entire fresh lumpectomies for specimen preparation (e.g.,

Agar and Histogel do well with processing but they do
not provide adequate support/adhesion for breadloafing
(unless a tissue adhesive coats the specimen, but this
becomes very hard to section).  Gelatin provides
excellent support, but it becomes very brittle and
unsectionable after processing.

Any help is very greatly appreciated.
