title: A method for preparing and handling cross-sections from early chick embryos for scanning electron microscopy.
abstract: A method is described for processing multiple cross-sections from early chick embryos for scanning electron microscopy. Embryos are cut through the desired regions. Sections are affixed to a coverslip with Duco cement and critical point dried by Freon 13 or liquid CO2. This method provides a reliable means for preparing multiple cross-sections from single embryos and eliminates the need for direct handling of brittle tissues after drying.
