A targeting vector was designed to insert a single loxP site 5' of the initiation codon in exon 1 and a loxP-flanked neomycin resistance (neo) cassette followed by a beta-galactosidase (lacZ) sequence downstream of exon 3. Mutant mice were bred to mice carrying Tg(rtetR-tetO-cre)40Mhz. Progeny were selected to retain loxP sites in introns 1 and 3, but an excised neomycin selection cassette. (J:98489, J:101977)
