Differentiation Solution
Supplier: SIGMA ALDRICH MICROSCOPY
Differentiation solution comprises acidified ethanol or isopropanol that is used to decolourise hematoxylin stain. The duration of exposure to the solution determines the degree of decolourisation. Differentiation is a crucial step in hematoxylin-eosin staining to achieve the proper colour contrast necessary for visualisation, by selectively removing excess hematoxylin from the tissue section and leaving behind the desired staining intensity.

Soluzione di montaggio non acquosa, Neo-Mount®
Supplier: Merck
Le soluzioni di montaggio non acquose, ad esempio Neo-Mount®, sono destinate al montaggio permanente e alla conservazione a lungo termine dei campioni. I vetrini processati nei laboratori patologici devono essere conservati fino a 10 anni, di conseguenza i risultati della colorazione devono essere stabili e non possono ammettere scolorimenti. La soluzione di montaggio anidra Neo-Mount® per microscopia è estremamente stabile e prodotta con solventi a base di miscele di idrocarburi alifatici. Poiché contiene un componente privo di aromatici in sostituzione dello xilene, la soluzione Neo-Mount® può essere combinata esclusivamente con Neo-Clear®. Non utilizzare lo xilene in fase di montaggio, in quanto causa l'offuscamento e la striatura dei vetrini. In aggiunta, posizionando i vetrini disidratati sulla carta filtrante per circa 1 minuto prima del montaggio, si impedisce l'eventuale eccesso di Neo-Clear®, in quanto sotto il vetrino coprioggetto potrebbero formarsi bolle di aria. Tale azione preventiva è da eseguire anche quando si montano i vetrini con macchine montavetrini; in quest'area, un'efficace eliminazione di NEO-CLEAR® si ottiene incubando i vetrini per un minuto in un rack per vetrini vuoto.

Epoxy Embedding Medium Kit
Supplier: SIGMA ALDRICH MICROSCOPY
The Epoxy Embedding Medium Kit is a very widely used embedding medium for electron microscopy. The embedding formulation originally published by Luft (1961) is excellent for both plant and animal tissues. Due to the low viscosity of the resin, it penetrates the tissue specimen faster than Araldite and other polymers. It hardens easily and uniformly at low temperatures with the addition of dodecenylsuccinic anhydride (DDSA), methyl nadic anhydride (MNA), and the accelerator 2,4,6-tris(dimethylaminomethyl)phenol (DMP-30). Slight shrinkage may occur during curing. This kit is useful for embedding a variety of tissues as a wide range of hardness can be obtained with this resin to suit a specific tissue type by using two different anhydride curing agents (DDSA and MNA).

Mounting Medium, CC/Mount™
Supplier: SIGMA ALDRICH MICROSCOPY
CC/mount is an aqueous based permanent mounting medium with a very high refractive index, which when applied to the stained tissue sections can store the tissue specimens permanently without the fading of the chromogens. Because of the superior refractive index of CC/mount, tissues mounted in this medium look like specimens mounted with organic based mounting media. No coverslipping is required with CC/mount. However, if coverslipping is required, dried CC/mount can be post mounted by using an organic based mounting medium. CC/mount permits the long-term storage of antigens localised using organic insoluble chromogen substrates, including AEC, DAB, Fast Red, BCIP/NBT, BCIP/INT and fluorescent dyes like FITC and phycobiliproteins. The high pH of CC/mount ensures increased stability of fluorescence intensity.
