Yolkless is transported in all tER-Golgi units. Cryosections of stage 9–10 WT egg chambers were labeled for the Gurken (15 nm) and Yolkless (10 nm). Yolkless, on its way to the plasma membrane, passes through all the tER-Golgi units of the ooplasm, at the D/A corner (A, together with Gurken), at the V/A corner (B) and at the posterior pole (P) (C). Arrows mark the specific Yolkless labeling. The 10-nm gold in A that is not marked by arrows is an artifact due, in this instance, to the double labeling technique. Bar, 200 nm.
