PAM sequences are underlined and highlighted in green. sgRNA targeting sites are highlighted in red. (B) Detection of sgRNA1:Cas9-mediated cleavage of Nr0b1, Ppar-γ, and Rag1 by PCR and T7EN1 cleavage assay. M, DNA marker; sg1, sgRNA1; sg2, sgRNA2; Con, control. (C) Sequences of modified Nr0b1, Ppar-γ, and Rag1 loci detected in COS-7 cells. At least 15 TA clones of the PCR products were analyzed by DNA sequencing. The PAM sequences are underlined and highlighted in green; the targeting sequences in red; the mutations in blue, lower case; deletions (−), insertions (+). N/N indicates positive colonies out of total sequenced. Cell  , DOI: ( /j.cell ) Copyright © 2014 Elsevier Inc. Terms and Conditions

4 Figure 2 sgRNA:Cas9-Mediated Modifications of Nr0b1, Ppar-γ, and Rag1 in Cultured Embryos (A) Detection of sgRNA1:Cas9-mediated on-target cleavage of Nr0b1, Ppar-γ, and Rag1 by T7EN1 cleavage assay. PCR products were amplified and subjected to T7EN1 cleavage assay. Samples with cleavage bands were marked with an asterisk “∗.” (B) DNA sequences of marked samples. TA clones from the PCR products were analyzed by DNA sequencing. Mutations in three PCR products (labeled with red asterisk) indentified by T7EN1 cleavage assay were not detected by TA sequencing because of limited amount of colonies. The PAM sequences are underlined and highlighted in green; the targeting sequences in red; the mutations in blue, lower case; deletions (−), and insertions (+). N/N indicates positive colonies out of total sequenced. See also Figure S1. Cell  , DOI: ( /j.cell ) Copyright © 2014 Elsevier Inc. Terms and Conditions

(B) PCR products of the target region of Ppar-γ and Rag1 in founders. Targeted region of Ppar-γ and Rag1 loci were PCR amplified from the umbilical cord genomic DNA of A and B founders. M, DNA marker; Con, control umbilial cord from wild-type cynomolgus monkey, which was born 9 days after birth of A and B. (C) Detection of sgRNA:Cas9-mediated on-target cleavage of Ppar-γ and Rag1 by T7EN1 cleavage assay. PCR products from (B) were subjected to T7EN1 cleavage assay. (D) Sequences of modified Ppar-γ and Rag1 loci detected in founders. At least 18 TA clones of the PCR products were analyzed by DNA sequencing.

9 Figure S3 Derivation of Targeted Allele Analysis by SNP Mapping, Related to Figure 4 (A) Schematic diagram of location of the single-nucleotide polymorphism (SNP) downstream of Rag1 sgRNA target site in founder twins’ parents. The Rag1 allele was amplified by primers 3.8F and 3.8R using the ear genomic DNA of founder twins’ parents as template. PCR products were sequenced by indicated primers. Four different SNPs were detected (purple). See also Table S1. (B) Genotype of founder twins’ parents was determined by TA cloning and sequencing of PCR products from (A). Father’s alleles were highlighted in red, mother’s in green. (C) Founder twins’ genotypes were determined by TA cloning and sequencing of PCR products amplified by primers 3.8F and 3.8R. (D) In founder B, mutations were detected in alleles from both parents. N/N indicates positive colonies out of total sequenced. Cell  , DOI: ( /j.cell ) Copyright © 2014 Elsevier Inc.
