A single loxP site was inserted 5' to the only coding exon, and a loxP-flanked hygromycin resistance cassette was inserted 3' to the exon. The hygromycin selection cassette was removed in ES cells by transient Cre expression leaving a single loxP site prior to the production of chimeric mice. (J:71969)
