This transgene consists of a hemagglutinin-tagged full-length (226 kb) wild-type mouse Lgi1 BAC construct containing the entire 41 kb genomic locus plus 163 kb 5' flanking and 21 kb 3' flanking genomic regions. A FRT flanked kanamycin selection cassette was removed by transfection with a FLP recombinase. (J:154129)
