SU(VAR)2-10 and lamin colocalize around the nuclear periphery in interphase neuroblasts and salivary gland cells. Indirect immunofluorescence showing simultaneous localization of SU(VAR)2-10 and nuclear lamin in interphase cells from third-instar larval neuroblasts (A–C), whole-mount salivary gland nuclei (D–F), and interphase S2 cells (G–I). In all panels, green is anti-SU(VAR)2-10 staining and red is anti-lamin staining. SU(VAR)2-10 and lamin are tightly colocalized in neuroblasts (A–C) and salivary gland cells (D–F), but the two do not colocalize in S2 cells (G–I). Note the SU(VAR)2-10-specific staining in the interior of neuroblast nuclei (A,C). (A–C,G–I) Bar, 5 μm. (D–F) Bar, 15 μm.
