Caption Generation of the Tjp1tm1.1Whun allele. (A) Targeting strategy using the Cre/loxP system. Schematic of the mouse genomic locus for Tjp1 (ZO-1 gene) is shown. The targeting vector introduces loxP-FRT-flanked Neo and F3-loxP-flanked Puro resistance cassettes 5' and 3', respectively, of Tjp1 exon 4. After Flp recombination, the conditional allele, Tjp1tm1.1Whun, contains a loxP-flanked exon 4 with residual 5' FRT and 3' F3 sites. Cre-recombination can be used to delete the floxed exon 4, yielding the constitutive KO allele. Genotyping PCR primers to identify wild-type, Tjp1-floxed heterozygous and homozygous animals are indicated with orange bars. The drawing is not to scale.
