Abstract
The zebrafish is a powerful vertebrate system for cell and developmental studies. Here we have optimized methods for fast freezing and processing of zebrafish embryos for electron microscopy. We show that in the absence of primary chemical fixation excellent ultrastructure, preservation of GFP fluorescence, immunogold labeling, and electron tomography, can be obtained using a single technique involving high pressure freezing and embedding in lowicryl resins at low temperature. As well as being an important new tool for zebrafish research, the maintenance of GFP fluorescence after fast freezing, freeze substitution, and resin embedding, will be of general use for correlative light and electron microscopy of biological samples.
