Which embedding medium is most commonly used for electron microscopy due to its hardness and stability under an electron beam?
Show answer and explanation
Correct answer: Epoxy resin
Epoxy resins provide the necessary support for cutting ultrathin sections and do not melt or vaporize when exposed to the heat generated by the electron beam in a vacuum.
