Implication

Laboratory study demonstrates that sandwiching tissue sections between protective films reduces electron beam heating artifacts, indicating improved structural preservation in microscopy.

Key Points

To identify the mechanisms causing electron beam damage and contrast loss in thin tissue sections and to evaluate methods for preventing heat-induced specimen destruction.
Analyzed the loss of methacrylate embedding material from exposed specimen surfaces compared to surfaces protected by substrate films during electron beam irradiation.
Coated both sides of thin tissue sections with thin protective films of formvar, collodion, or carbon prior to electron microscope examination.
Loss of embedding material was higher at exposed section surfaces than at surfaces supported by a substrate film.
Covering both surfaces with formvar, collodion, or carbon improved specimen appearance, decreased distortion, and reduced tissue mass loss by resisting surface-tension forces in beam-softened methacrylate.
