FIG. 5.  Detection of thyroglobulin in the mouse thyroid by immunogold electron microscopy. After wash with phosphate-buffered saline–bovine serum albumin (PBS-BSA 1%), ultrathin sections (0.1 μm) were incubated overnight with a rabbit polyclonal anti-thyroglobulin antibody (1/300, DAKO). Sections were then rinsed and incubated for 30 minutes with a 12-nm colloidal gold affinity pure goat anti-rabbit IgG (Jackson, , lot no ). Sections were postfixed with 2.5% glutaraldehyde for 5 minutes and counterstained. They were examined with a Zeiss 109 transmission electron microscope. (A) Negative control obtained by omission of primary antibody. (B) Thyroglobulin was detected as small gold particles in the colloid limited by flat epithelial cells.
