A targeting vector containing a FRT site-flanked neo cassette and a loxP site was inserted downstream of exon 2 (the first coding exon) of the targeted gene, and another loxP site was inserted upstream of exon 2. Flp-mediated recombination removed the FRT-flanked neo cassette leaving exon 2 floxed. (J:227400)
