CRISPR/Cas9-mediated generation of a POLD1-knockout model. (A) Schematic overview of the targeting procedure, displaying CRISPR/Cas9-mediated integration of the repair template in exon 2a of the POLD1 locus. (B) PCR detecting the POLD1-KO and –WT alleles as well as (C) the Cre/loxP-mediated excision of the puromycin resistance cassette. Dashed lines indicate cropping, and the original gels are displayed in Figure S1.
