LHA, left homology arm; RHA, right homology arm. B , PCR genotyping strategy for selecting homozygously tagged DFN-IRS2 . First-round primers complementary to the modified loci were used to amplify wild-type alleles (523 bp) and knock-in alleles (1663 bp). Second-round primers complementary to IRS2 outside the donor plasmid homology arms were used in long-distance PCR for wild-type alleles (2260 bp) and knock-in alleles (3400 bp). Indicated amplicon sizes confirm the homozygous integration of the tags.
