Araldite® M, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
Araldite® is an epoxy resin commonly used for embedding. It is basically free from polymerization damage and the plastic does not sublime in the microscope, hence providing continual support and preservation of fine detail.[1] It is composed of araldite M or CY 212, dodecenyl succinic anhydride, dibutyl phthalate and 2,4,6-tridimethylamine methyl phenol.

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.
