Fig. 5. Rad18Sc protein is associated with XY body chromatin of pachytene and diplotene spermatocytes. Rad18Sc is stained using anti-Rad18Sc (green) and axial elements and lateral elements of SCs are stained with anti-Sycp3 (red) in zygotene (A), pachytene (B), early diplotene (C) and diplotene (D) spermatocytes. Bar, 20 µm.
