Embedding Medium ERL-4221D

(Epoxycyclohexylmethyl-3,4-epoxycyclohexylcarboxylate, Epoxy embedding medium, Spurr Embedding Medium)
C14H20O4Mr 252CAS [2386-87-0]

ERL-4221D (Epoxycyclohexylmethyl-3,4-epoxycyclohexylcarboxylate) is a cycloaliphatic epoxy resin used as an embedding medium for electron microscopy. ERL-4221D is a less toxic substitute for the classical SPURR embedding medium component ERL 4206. SPURR-Mixture has a low viscosity which facilitates rapid prenetration into tissues. It is often used for highly vacuolated plant cells and tissues with hard lignified cell walls, for brain tissue as well as for tissues with dense structures like minerals and bones.
