Sheet Mica—A Nonadherent Carrier for Surface Culture of Cells to Be Embedded in Epon

With epoxy resins as embedding media, more richness in detail in electron micrographs can be gained than with methacrylate. For the embedding of surface-cultured cells, however, the use of Epon has been impractical because it cannot be readily separated, after hardening, from the glass surfaces on which cells are usually cultured.
