Fluorescence antifade mounting media and CoverGrip™ coverslip sealant, EverBrite™

Fluorescence antifade mounting media and CoverGrip™ coverslip sealant, EverBrite™

Supplier: Biotium

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.

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.

Milieu de montage anhydre Neo-Mount®

Milieu de montage anhydre Neo-Mount®

Supplier: Merck

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.
