TALEN treatment of primary T cells enables simultaneous and highly efficient processing of TRAC and dCK genes. (a) Overall gene architectures of dCK and TRAC open reading frames. Exons (dark blue) and introns (light blue) are indicated. dCK and TRAC TALEN targets are displayed and underlined. The TALEN binding sites and spacer sequences are respectively displayed in upper and lower cases letters. (b) Genotypic characterization of TALEN-mediated inactivation of dCK and TRAC genes by high throughput DNA sequencing. T cells treated with dCK and TRAC TALEN were allowed to grow for 6 days, their genomic DNA was extracted, amplified using TRAC or dCK specific PCR amplicons and analyzed by high throughput DNA sequencing. The frequencies of indels generated at TRAC and dCK locus are indicated.
