<p>Panels (A–F) show GFP fluorescence for Stwl-GFP in polytene chromosomes (A–C) and in diploid cells (D–F). (A and D) show DNA labeled in blue by DAPI. Stwl-GFP is shown in green in panels (B and E) while panels (C and F) show the merged images. Stwl localization appears as dots around the periphery of diploid cells; DAPI (G), α-Stwl (H), α-Lamin Dm0 (I) and merged (J). Panels (K–N) show polytene chromosomes labeled with Stwl and CP190 antibodies indicating little overlap between the two proteins, DAPI (K), α-Stwl (L), α-CP190 (M) and merged (N).</p
