  • Title: Preparation of bone for high-voltage electron microscopic radioautography.
    Author: Pylypas SP, Schurath RM, Johnson RB.
    Journal: J Electron Microsc Tech; 1990 Apr; 14(4):324-8. PubMed ID: 2332807.
    Abstract:
    This paper presents a reliable technique for the preparation of radioautographic specimens for study by high-voltage electron microscopy. Tissues are fixed by ventricular perfusion of aldehydes, sectioned, collected on slides, and coated with nuclear track emulsion using a coating machine. Sections are developed after 17 weeks' exposure in either undiluted Microdol-X or diluted D-19 developer, fixed in 25% sodium thiosulfate, and stained through the emulsion with uranyl acetate in absolute methanol and aqueous lead citrate. The technique produces sections of even thickness and staining density with negligible numbers of background grains and non-specific labeling. In this report, the efficacy of this technique for the study of the periosteal surface of demineralized alveolar bone specimens is demonstrated.
