Targeted disruption of the murine
Fancg gene. (A) Schematic representation of the murine Fancg gene showing 14 exons. The targeted allele has exons 2 to 9 replaced by the FRT-flanked neomycin cassette. There are translational stop codons in 3 reading frames 5′ to the neomycin cassette to terminate any potential upstream translation. Primers used for genotype and RT-PCR are indicated. (B) PCR genotype of mouse tail DNA using primers indicated in panel A. Primers Gex5F and Gex6R amplify a 285 base pair (bp) product specifically from the wild-type allele (WT), whereas primers Psv and G40 amplify a 580 bp product specifically from the mutant allele (MT). (C) RT-PCR of the wild-typeFancg mRNA using primers Gex5F and Gex6R fromFancg+/− testes but not fromFancg−/− testes. A 360 bp RT-PCR product of β2-microglobulin was used as an internal control (β2M).
