Fig. 2. Germline transmission of Sleeping Beauty transposon transgenes in Xenopus tropicalis. Six transgenic founder animals have been identified to date. The -actin promoter- CMV enhancer (CAGGS) drives robust wide- spread expression of green fluorescent protein (GFP) in F1 progeny from each founder line. The tadpoles were photographed at approximately stage 40, ventral view, 35 magnification. The aperture setting and exposure time were the same for each image. a: Nontransgenic 4M F1 tadpole. Note, autofluorescence of the gut. b: GFP-positive 4M F1 sibling of the tadpole de- picted in panel a. c: 7M F2 GFP-negative tad- pole. d: 7M F2 GFP-positive tadpole sibling of tadpole in panel c. e: 5M F2 GFP-positive tad- pole. f: 6M F1 GFP-positive tadpole.
