CUTANA™ CUT&Tag provides impressive gains in histone PTM mapping compared to ChIP-seq, the traditional chromatin mapping assay.
How does CUT&Tag work?
Cleavage Under Targets and Tagmentation (CUT&Tag) is a novel immunotethering-based chromatin mapping assay.
In CUT&Tag, a fusion of protein A, protein G, and Tn5 transposase (pAG-Tn5) is used to cleave and add sequencing adapters at antibody-bound chromatin. Tagmented DNA is selectively amplified by PCR and sequenced.
This strategy eliminates chromatin fragmentation, IP, and library prep, streamlining CUT&Tag workflows vs. ChIP-seq. Resulting profiles have improved signal over background using small numbers of cells and deliver major cost savings.

The CUTANA™ CUT&Tag Protocol & Ideal Applications
EpiCypher makes it easy to customize your CUT&Tag experience by offering an all-inclusive kit, individual reagents & tools, and a user-friendly CUT&Tag protocol.
Both the CUT&Tag protocol and kit manual feature our rapid, one-tube strategy and extensive troubleshooting guidance. These resources are also routinely updated to reflect advances by EpiCypher scientists. The current protocol and kit are optimized for:
- Histone PTMs*
- Fresh, frozen, and cross-linked nuclei (preferred) or cells
- Low inputs (100,000 down to 10,000 starting cells)
- Reduced sequencing depths (5-8 million reads)
* We recommend CUTANA CUT&RUN assays to map chromatin-associated proteins. Trying to decide between CUT&RUN and CUT&Tag? Read our blog to learn more.

- Kaya-Okur et al. CUT&Tag for efficient epigenomic profiling of small samples and single cells. Nat. Comm. 10, 1930 (2019). (PMID: 31036827)
This paper introduces CUT&Tag methodology, as developed by the Henikoff laboratory at the Fred Hutchinson Cancer Research Center. It describes how the Tn5 fusion proteins works, demonstrates the application of CUT&Tag for histone PTM and chromatin factor profiling, and reveals major advantages of this new technology. Specifically, they use CUT&Tag to generate high-quality histone PTM profiles from single cells, a major advancement for the epigenetics field. - Kaya-Okur et al. Efficient low-cost chromatin profiling with CUT&Tag. Nat. Protoc. 15, 3264-3283 (2020). (PMID: 32913232)
Here, the inventors of CUT&Tag provide a highly detailed description of their optimized CUT&Tag protocol, citing EpiCypher’s pAG-Tn5 as the suggested commercial vendor of the enzyme. The protocol highlights critical steps, includes a troubleshooting FAQ table, and shows example results. - Henikoff et al. Efficient transcription-coupled chromatin accessibility mapping in situ. by nucleosome-tethered tagmentation. Elife 16;9:e63274.(2020). (PMID: 33191916)
The inventors of CUT&RUN / CUT&Tag technology leveraged EpiCypher’s pAG-Tn5 and CUT&RUN compatible histone PTM antibodies to develop a modified version of CUT&Tag for chromatin accessibility mapping. Importantly, this new method generates robust, high-quality profiles using only 3-5M reads/samples (vs. 20-30M reads for standard ATAC-seq). - Janssens et al. Automated CUT&Tag profiling of chromatin heterogeneity in mixed-lineage leukemia. Nat. Genet. 53, 1586-1596 (2021). (PMID: 34663924)
Assay automation is a major feature of CUT&Tag, as this will enable higher throughput for clinical research projects. In this study, Janssens et al. develop an automated CUT&Tag platform and use it to map oncofusion proteins, transcription factors, and histone PTMs in samples from leukemia patients. They also modified their approach for single cell analysis to assess inter- and intra-tumor heterogeneity. Janssens et al. CUT&Tag2for1: a modified method for simultaneous profiling of the accessible and silenced regulome in single cells Genome Biol. 23, 81.(2022). (PMID: 35300717)
CUT&Tag2For1 is an innovative application of CUT&Tag profiling technology that allows simultaneous, high-resolution mapping of transcription initiation (RNA Pol II phospho S5) and repressive domains (H3K27me3) in single cells or bulk populations. Mapping multiple chromatin features in a single reaction is important when cell numbers are limiting, including biopsy studies and clinical research.
