Comparison of GFP expression patterns controlled by the Gal4^repo driver from the BDSC line #7415 with the Repo expression pattern in the CNS and eye-antennal imaginal discs from third-instar larvae. Maximum intensity projections of confocal images of tissues stained with anti-Repo antibodies are shown. a-d Substantial overlap between the GFP and Repo signals in the CNS and eye imaginal discs. e-h Perfect colocalizations of the GFP and Repo signals in the eye imaginal disc and optic stalk. i-l Colocalization of the GFP and Repo expression patterns in the VNC. m-p Overlapping of the GFP and Repo signals in the central brain and optic lobes; note that the GFP expression pattern seems to be broader than the Repo immunostaining pattern. CB, central brain; OL, optic lobe; ED, eye imaginal disc; VNC, ventral nerve cord. Scale bars: a-d, 200 μm; e-p, 100 μm
