CUT&RUN LoV-U of beta-catenin, TCF/LEF transcription factors and histone modifications in HEK293T and mouse embryonic hindlimb tissue at 11.5 days post coitum

In our attempts to profile different regulators of the WNT/b-catenin transcriptional complex, CUT&RUN failed to produce consistent binding patterns of the non-DNA-binding b-catenin. We developed a modified CUT&RUN protocol, which we refer to as LoV-U (Low Volume and Urea), that enables the generation of robust and reproducible b-catenin binding profiles. CUT&RUN-LoV-U can profile all classes of chromatin regulators tested, as shown by datasets targeting the TCF/LEF transcription factors and various histone modifications. CUT&RUN-LoV-U uncovers direct WNT/ß-catenin target genes in human cells, as well as in ex vivo cells isolated from developing mouse tissue.
