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.

Zinc formalin fixative is a non-precipitating fixative. This fixative is compatible with histochemical, immunochemical and special stains. It may be used with automated tissue processors and also in manual methods. The zinc chloride component of the formulation increases the rigidity of cellular components to withstand subsequent processing, sectioning and staining procedures. Tissue specimens initially fixed using 10% neutral buffered formalin solution may be post-fixed using the zinc formalin fixative.

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).

Les produits de montage anhydre, telles que Neo-Mount®, doivent être utilisés pour le montage permanent et le stockage à long terme d'échantillons. Les lames traitées dans les laboratoires d'anatomo-pathologie devant être stockées jusqu'à 10 ans, les résultats de coloration doivent être stables et une décoloration n'est pas acceptable. Le milieu de montage anhydre Neo-Mount® est un milieu de montage pour microscopie à la coloration extrêmement stable, fabriqué avec des solvants à base de mélanges d'hydrocarbures aliphatiques. Il contient un substitut non aromatique du xylène, par conséquent, Neo-Mount® doit être combiné exclusivement avec Neo-Clear®. Le Xylène doit être évité dans l'étape de montage, car il entraîne une opacification des lames et laisse des traces. En outre, en plaçant les lames déshydratée sur papier filtre pendant environ 1 minute avant montage, tout excès de Neo-Clear® peut être évité, étant donné que des bulles d'air peuvent apparaître sous la lamelle couvre-objet. La même condition préalable doit également être respectée lors du montage des échantillons à l'aide d'une machine de montage automatique ; dans ce cadre, le NEO-CLEAR® peut être éliminé de la façon la plus efficace par incubation des lames pendant une minute dans un portoir à lames vide.

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.

EverBrite™ mounting media are anti-fade mountants for preserving fluorescence during microscopy. EverBrite™ mounting media prevent rapid photobleaching of fluorescein, rhodamine, and cyanine based dyes and are optimally formulated for use with Biotum’s CF™ dye conjugates. Unlike Vectashield® EverBrite™ mounting media is compatible with Cy® dyes such as Cy®2, Cy®3 and Cy®5. EverBrite™ mounting medium is a wet-set medium while EverBrite™ hardset mounting medium cures overnight to form a hard permanent seal with the coverslip, eliminating the need to seal coverslip edges with nail polish or other sealants. Both formulations are available with DAPI for blue fluorescent nuclear counterstaining without an additional staining step.
