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