Immunogold electron microscopic localization of Rhcg in C57BL/6 non-A, non-B cell. A: low-power magnification image of a non-A, non-B cell in the CNT. B: high-power image of the apical portion of this cell demonstrating apical plasma membrane Rhcg immunolabel. C: absence of basolateral Rhcg immunolabel in the non-A, non-B cell (arrowheads), whereas abundant basolateral plasma membrane Rhcg immunolabel is present in the adjacent CNT cell (arrows). *, Basement membrane. Rhcg antibody A was used in these studies and results are typical of findings in at least 5 mice.
