Generation of TonEBP-floxed mice. Panel A. Targeting Strategy. TonEBP-floxed mice were generated by ingenious Targeting Laboratory, Inc. (00 Smithtown Avenue, Ronkonkoma, NY 779) using standard gene-targeting techniques. The targeting construct was designed such that the short homology arm extends about. kb to exon, whereas the long homology arm extends about. kb to exon. A single loxp-site, containing an engineered -site for Southern Blot analysis, was inserted bp upstream of exon and a loxp/frt-flanked Neo cassette was inserted 0 bp downstream of exon. Thus the target region is bp long and includes exon. The figure is not exactly drawn to scale! BA (C7BL/ x 9/SvEv) hybrid embryonic stem cells were electroporated with 0µg of linearized targeting vector and selected with G8 antibiotic. Panel B. Screening and analysis of the retention of the third loxp-site. (Initial Screening was carried out by PCR, using reverse primer -ACGCCAGTGTCATGTTGTTG- downstream of the short arm and forward primer - GCATAAGCTTGGATCCGTTCTTCGGAC- within the Neo cassette generating a product of.7 kb in case of homologous recombination; data not shown). Four PCR-positive clones were expanded (indicated by an x) and retention of the third loxp-site upstream of exon was proven by PCR with primers -GTAACCATGATTAGTCTTTTAGCTTTATG- and - GTTCTGAGAATCCAAAGCACAAC- generating a bp long fragment from the WT-allele and an additional 9 bp long fragment from the floxed allele. Panel C. Southern Blot analysis. Further confirmation of the expanded homologous recombinant clones was performed by two different Southern Blot experiments. Left panel: -digested DNA was hybridized with a 7 bp long probe (probe primers: - TTTTGTGGCTAAGCACAGTCCC- and -CATACTGCAGCTCTGCTCAGATTC- ), which was targeted against the external region, detecting a 9. kb long WT-fragment and the.7 kb long floxed fragment. Right panel: -digested DNA was hybridized with a bp long probe (probe primers: -TGACTGCCCTCAACAGTTCATTTG- and -ATTCAGGATCTGCTACCACCACTG- ) targeted against the internal region, detecting a 9. kb long WT- and the. kb long floxed fragment. In both Southern Blot experiments, DNA from C7Bl/ (B), 9/SvEv (9), and BA (C7Bl/ x 9/SvEv; Hyb) mouse strains were used as wild type controls. Confirmation of Neo-deletion and standard Genotyping procedures. Targeted itl BA (C7BL/N x 9/SvEv) hybrid embryonic stem cells were microinjected into C7BL/ blastocysts. Resulting chimeras with a high percentage agouti coat color were mated to C7BL/ homozygous FLP mice to remove the Neo cassette. Primers Ndel ( -GTTGTGCTTTGGATTCTCAGAAC- ) and Ndel ( -CTTCTACCCTTCTATTTCAGGAAGC- ) were used to confirm Neo-deletion indicated by a 7 bp fragment. DNA still containing Neo is not amplified since the fragment would be too long. The same primer pair also generates a 97 bp long WT-fragment. Thus it can be routinely applied for standard genotyping. Genotyping primers are not depicted within the figure.
