Summary
The electron microscopic demonstration of alkaline phosphatase (ALP) was carried out on the trigeminal ganglion of the rat using the calcium lead modification method by Gomori (Gomori, 1952; Molnar, 1952).
The ALP reaction was localized on the junction of capsular cells and nerve cells, in the cytoplasm of some dark capsular cell and in that of the endothelial cell: The enzymatic reaction products (1) existed throughout the entire length of the junction of clear cells and capsular cells, (2) aggregated at some points of the junction of dark cells and capsular cells, (3) existed on the smooth and/or rough surfaced endoplasmic reticulum and on the ribosomes of some dark capsular cells.
