When sectioning frozen tissue for rapid surgical biopsy diagnosis or for research (typically in Histochemistry), the tissue sample must be firmly attached to the microtome stage or chuck. Embedding material such as OCT are preferred as these also provide a supportive and protective aid to sectioning.

PolyFreeze is a water-soluble support matrix and a form of embedding medium for frozen sectioning. PolyFreeze sections flawlessly at routine frozen specimen thickness of 5-6 μ and leaves no slide residue. It provides for -20 ºC cryostat sectioning in rapid set embedment. This medium freezes quickly supporting the tissue for sectioning at 3 mm and up with no cracking of the matrix at temperatures from -8 °C to -25 °C.

Entellan® new is a new mounting medium for cover slippers and is specially suited for commercial automated mounting instruments that operate with cover slippers. Its viscosity ranges between 250 and 600 mPas, 1,00869 has a small viscosity range. This narrow viscosity range improves and accelerates the application, as neither the dropping rate nor the volume need to be reset after the first run with a new bottle of Entellan® new.

CytoLiner™ Fixed cell membrane dyes are novel lipophilic fluorescent dyes developed specifically for selective plasma membrane staining in fixed cells for microscopy. The dyes are engineered for robust and consistent staining of formaldehyde-fixed cells, and are suitable for downstream immunofluorescence staining protocols.

Supplier: Thermo Fisher Scientific

This gel loading dye contains two different dyes bromophenol blue and xylene cyanol FF for visual tracking of DNA migration during electrophoresis. The presence of glycerol ensures that the DNA in the ladder and sample forms a layer at the bottom of the well. The EDTA included in the solution binds divalent metal ions and inhibits metal-dependent nucleases.

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).

Water-free mounting media, such as Neo-Mount®, should be used for permanent mounting and long-term storage of samples. Slides processed in pathologyl laboratories need to be stored up to 10 years, whereby the staining results need to be stable and fading-out is not acceptable. Neo-Mount®, anhydrous mounting medium for microscopy is an extremely colour-stable mounting medium for microscopy, which is produced with solvents based on mixtures of aliphatic hydrocarbons. It contains an aromatic-free substitute for xylene, thus, Neo-Mount® needs to be combined with Neo-Clear® exclusively. Xylene must be avoided in the mounting step, as it will cause the slides to become cloudy and streaked. In addition, by placing the dehydrated slides on filter paper for approx. 1 minute prior to mounting, any excess Neo-Clear® should be circumvented, as air bubbles might arise under the cover slip. The same pre-condition should also be met when mounting specimens using cover slip machines; in this area, Neo-Clear® can be most efficiently eliminated by incubating the slides for 1 minute in an empty slide rack.
