    Generation of aspa lacZ mice by homologous recombination. A, Genomic structure of the murine aspa locus, which spans 6 exons (black boxes). Homologous recombination of the targeting vector inserts the βgeo cassette (blue box), encoding β-Galactosidase (lacZ), into intron 1 of the intact aspa gene. This cassette is flanked by frt-sites (green circles). Additional loxP sites flank exon 2 (red triangles). The vector includes a DTA cassette for negative selection. In the targeted allele, exon 1 is spliced to the splice acceptor site preceding βgeo, and transcription is terminated at the introduced pA site. The conditional aspa flox allele is produced by breeding aspa lacZ mutants to FLP-deleter mice [40] for recombination of the βgeo cassette in vivo . Note that frt and loxP sites are not drawn to scale. βgeo, β-galactosidase-neomycin resistance cassette; SA, splice acceptor; pA, polyadenylation site, DTA, Diphteria toxin gene. B, For Southern blot analysis genomic DNA was digested with SmaI/ApaI. The neo probe (white box in A) detected the expected 7.5 kb band in heterozygotes and homozygotes. C, Genomic PCR of littermates with primers 1 3 produces the expected amplicons in aspa +/+ (336 bp), aspa lacZ/+ (387 bp and 336 bp) and aspa lacZ/lacZ (387 bp) animals. The upstream loxP site was detected by PCR with primers 1 2 yielding a 307 bp band. D, Q-RT-PCR using a TaqMan probe for quantification of aspa mRNA levels in brains of aspa +/+ , aspa lacZ/+ , and aspa lacZ/lacZ mice (n = 3) confirms the attenuation of transcription downstream of exon 2 in the targeted allele. E, Representative Western blot of whole brain lysates of a spa +/+ , aspa lacZ/+ and aspa lacZ/lacZ mice (aged 4 months, n = 3). The 37 kD protein ASPA was detected in aspa +/+ and aspa lacZ/+ mice but not in aspa lacZ/lacZ mutants. β-Galactosidase is expressed in aspa lacZ/+ and aspa lacZ/lacZ brain but not controls. α-Tubulin was used as loading control.
