General description

Epoxy embedding medium is generally used for biological tissues during study by electron microscopy. Usually, it consists of three components; Epon 812 resin, an anhydride hardener and an accelerator.
additional information see 45359 Epoxy Embedding Medium kit

Application

It was used during transmission electron microscopy done for the analysis of epithelial cells; during a study performed to understand the epithelial cell growth and stratification in minimal culture conditions.

Impaired macroautophagy/autophagy is involved in the pathogenesis of hepatic fibrosis. However, how aberrant autophagy promotes fibrosis is far from understood. Here, we aimed to define a previously unrevealed pro-fibrotic mechanism for the stress protein TRIB3 (tribbles pseudokinase 3)-mediated autophagy dysfunction.
