Fig. 7. Immunofluorescent staining of synchronised mouse L929 cells with antibody against P68. Cells were stained with anti-P68 (green) and counterstained with DAPI (red pseudocolour) to reveal the location of p68 with regard to chromocentres, and were captured in G1 (A), early S (B), late S (C), G2 (D). The first column shows merged images. Bar, 10 µm.
