| molecularNote | An F3-flanked puromycin resistance cassette with a 3' loxP site were inserted upstream of exon 2. An FRT-flanked neomycin resistance cassette with a 5' loxP site was inserted downstream of exon 2. Flp-mediated recombination removed both selection cassettes. Cre-mediated recombination removed exon 2. |
