Abstract

The identification of TBX5-related regulatory sequences in genes essential for heart development is hampered by the absence of antibodies which allow precipitation of TBX5:DNA complexes. Employing CRISPR/Cas9 technology, we have inserted a FLAG-tag sequence at the end of exon 9 of the TBX5 gene prior to the stop codon by homologous recombination. The translated TBX5-FLAG fusion protein of the three iPSC lines can effectively be precipitated by anti-FLAG antibodies and, thus, allow the detection of specific TBX5-binding sites and their associated genes.
