General description

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).


Epoxy Embedding Medium Kit has been used in the following applications:

  • to study the role of NDRG2, an essential colonic epithelial barrier regulator, in gut homeostasis maintenance and colitis-associated tumor development
  • to study the interaction of polymer scaffold nanofibers with growing cells
  • to study the morphological characterization of postembryonic development of blood–spleen barrier in ducks
  • to understand the role of NOD1/NOD2 receptors in Fusobacterium nucleatum-mediated neutrophil extracellular traps

Features and Benefits

  • Excellent medium for embedding a wide variety of tissues, including both plant and animal.
  • Facilitates rapid embedding (less than 3 hours).
  • Low viscosity facilitates rapid tissue penetration.
  • Desirable hardness is easy to obtain to suit a specific tissue type.
