| Genetic information | In collaboration with Genoway (Lyon, France; project number genOway/EV/TIN1-Kcnj8070206), we targeted exon 2 of the mouse Kcnj8 gene. Using homologous recombination a loxP site together with a FRT flanked neomycin selection cassette was inserted within intron 1 upstream of exon 2. Exon 2 contains the ATG translation initiation codon and another loxP was inserted distal to exon 2 in intron 2. The targeting construct was transfected into E14Tg2a ES cells derived from 129P2/Ola mice and one positive clone was isolated that had the intended 5’ and 3’ homologous recombination event in one allele. There were no other randomly integrated copies of the targeting vector. This ES cell clone was injected into C57BL/6J blastocysts and implanted into pseudo-pregnant females. A number of male chimaeras were bred with Flp deleter mice to remove the neomycin cassette and generate Kir6.1(+/flx) mice. The Kir6.1(+/flx) were crossed with C57BL/6 Cre deleter mice (which ubiquitously express the cre recombinase) to develop mice with global genetic deletion of one allele of Kir6.1 (Kir6.1+/-). Kir6.1 +/- and Kir6.1 +/flx were backcrossed onto a C57BL/6 background for at least six generations. Homozygous KO (Kir6.1-/-) mice were generated by cross-breeding of the Kir6.1+/- heterozygous mice. |
