Rapid method for resectioning of light microscopy sections for electron microscopy

A rapid method is described for obtaining ultrathin sections from light microscopy sections. Five‐micrometre epoxy sections, heat‐flattened to slides, were affixed to the tips of plastic blocks by light‐curable dental bond, and cured while still on the microscope stage by illumination with blue light for 2 min. Sections were detached from the slides by rapid cooling and then resectioned for electron microscopy.
