Figure 5.
The SETβ signal leaves centromeres in metaphase. (A) HeLa cells released from RO3306 and then treated with colcemid (top and B–D), with MG132 (bottom and H and I), or not treated (middle and E–G) were fixed and stained with anti-SETβ (green), Sgo2 (red), and Cenp-C (blue) antibodies. DAPI was used to visualize DNA. Kinetochore pairs in white enclosures are shown in large scale. Scale bars, 5 μm. (B–I) Line scans of individual sister kinetochores/centromeres in the white enclosures are shown from left to right.
