Immunogold labelling

Two images produced using immunogold labeling and transmission electron microscopy: (A) Gold particles are marking mtDNA near the mitochondria (B) mtDNA  marked with gold particles after extraction.[1]

Immunogold labeling or Immunogold staining (IGS) is a staining technique used in electron microscopy. This staining technique follow the same patterns of the Indirect immunofluorescence : colloidal gold particles are most often attached to secondary antibodies which are in turn attached to primary antibodies designed to bind a specific antigen or other cell component. Gold is used for its high electron density which increases electron scatter to give high contrast 'dark spots'.
