Confocal images showing an external (D) and internal (E) focal plane of a 1.5-fold
dlg-1::gfp transgenic embryo after immunostaining with anti-GFP antibody. Weak background fluorescence could often be seen around the pharyngeal lumen and rectum (arrowheads in E; these expressing cells have not been identified). (F-H) GFP fluorescence of a young
dlg-1::gfp transgenic adult showing expression in epithelial cells of the pharynx (arrow in F), intestine (arrowhead in F and large arrow in H), vulva (large arrow in G), uterus (arrowheads in G), spermatheca (long arrows in G), rectum (long arrow in H) and epidermis (arrowhead in H). Scale bars, 50 um (F-H); 10 um (D,E).
