(A) Genotyping of Tet1 single-targeted mice.
(B) Upper: genotyping of Tet2 single-targeted mice. RFLP analysis; lower: Southern blot analysis.
(C) The sequence of both alleles of targeted gene in Tet1 biallelic mutant mouse 2 and Tet2 biallelic mutant mouse 4.
(D) Genotyping of Tet1/Tet2 double-mutant mice. Analysis of mice 1 to 12 is shown. Upper: RFLP analysis; lower: southern blot analysis. The Tet1 locus is displayed on the left and the Tet2 locus on the right.
(E) The sequence of four mutant alleles from double-mutant mouse 9 and 10. PAM sequences are labeled in red.
(F) Three-week-old double-mutant mice. All RFLP and Southern digestions and probes are the same as those used in Figure 1. See also Figures S2 and S3.
