acd-5::mKate2 C-terminal fusion showed expression in the intestinal epithelial cells, localising to the apical membrane, as confirmed by co-localisation with an apical membrane marker (OPT-2::GFP [Nehrke, 2003]) and by comparing the localisation with that of markers for the intestinal cytoplasm (Pdel-5::GFP) and lumen (ingested fluorescent dye, DiO.
