Immuno-electron microscopy and electron microscopic in situ hybridization for visualizing pirna biogenesis bodies in Drosophila ovaries

Abstract

Immuno-electron microscopy and electron microscopic in situ hybridization are powerful tools to identify the precise subcellular localization of specific proteins and RNAs at the ultramicroscopic level. Here we describe detailed procedures for how to detect the precise location of a specific target labeled with both fluorescence and gold particles. Although they have been developed for the analysis of Drosophila ovarian somatic cells, these techniques are suitable for a wide range of biological applications including human, primate, and rodent analysis.
