CUT&Tag Sequencing

CUT&Tag (Cleavage Under Targets and Tagmentation) Sequencing is a next-generation sequencing-based method for the study of protein-DNA interactions. CUT&Tag is a new generation of ChIP-Seq without suffering from a number of practical and economical limitations, for it does not require cells to be lysed nor chromatin to be fractionated.


Compared with traditional ChIP-Seq methods, CUT&Tag eliminates the need for cross-linking, sonic interruption, end smoothing, and splicing. Therefore, CUT&Tag is time-efficient, requires less sample volume, has a low background signal, and is reproducible. Researchers can even use CUT&Tag for single-cell sequencing. Combined antibody-targeted cleavage induced by protein A-Tn5 fusion with high-throughput DNA sequencing, CUT&Tag identifies binding sites for DNA-associated proteins. Once the antibody binds to the target protein (transcription factor, histone, etc.), protein A binds directly to the antibody and carries a Tn5 transposase that specifically cuts the DNA fragment near the target protein and joins the DNA fragment, allowing for high-throughput sequencing after library construction. It can be used to precisely map the global DNA binding sites of any protein of interest. CUT&Tag is a prominent technology that can turn the study of protein-DNA interactions into a routine operation similar to PCR reactions, which will have revolutionary implications for the study of gene regulation, epigenetics, and many other fields.
