(D-G)
catp-1 expression profile. Detection of GFP fluorescence by confocal (D) and epifluorescence microscopy (E) in transgenic larvae expressing Pcatp-1(C. briggsae)::GFP.
catp-1 is expressed in the hyp (white arrowheads) and Pn.p cells of the epidermis (D) and in the duct cell of the excretory system (E-G). No GFP expression was detected in the lateral cells of the epidermis (seam cells: black arrowheads). In (G), the GFP image (E) of the duct cell was overlayed on a Nomarski picture of the same field (F) where the excretory duct is visible (black arrow). Scale bars: 20 μm (D); 5μm (E-G).
