FIG. 6.

CD1D knockout pigs generated by CRISPR/Cas9 system injected into zygotes. A) PCR amplification of CD1D from knockout pigs; 166-1 shows a mosaic genotype for CD1D. 166-2, 166-3, and 166-4 do not show a change in size for the amplicon, but sequencing of the amplicon revealed modifications. B) PCR amplification of the long-range assay showed a clear deletion of one allele in piglets 166-1 and 166-2. C) Image of CD1D knockout pigs with surrogate. D) Sequence data of CD1D knock out pigs. The atg start codon in exon 3 is in bold and also lower case.
