Using BAC RP23-145I16, a loxP site was inserted into intron 1 and an FRT site flanked neomycin resistance gene cassette and a second loxP site into intron 2. The neo cassette was removed through subsequent flp-mediated recombination, leaving a conditional-ready allele with exon 2 floxed. (J:243582)
