Fig. 9. Ultrastructural localization of p66/ACF. Sections of rat liver were
prepared and reacted with p66/ACF as described in
Fig. 8. (A) P66/ACF was
associated with the surface and borders of heterochromatin in the nucleus
(magnification, 22,500x). Cytoplasmic p66/ACF was predominantly
associated with the outer surface of the endoplasmic reticulum and B, to a
lesser extent with the outer surface of the Golgi (magnification,
30,000x). ER, endoplasmic reticulum; Mt, mitochondria; Nu, nucleus.
