Summary
The fine structural localization of a peroxidase activity in the rat thyroid follicular epithelial cell was studied by histochemistry at electron microscopic level. The reaction product is recognized chiefly in the cisternae of the elements of granular endoplasmic reticulum and of nuclear envelope. Golgi vesicles or apical small vesicles, mitochondria, and dense granules are sometimes positive for this reaction. The relationship between the fine structural localization of peroxidase and the site of the iodination of thyroglobulin is discussed.
