CUTANA CUT&Tag Assays

CUTANA™ CUT&Tag: Ultra low input chromatin mapping assays

Cleavage Under Targets and Tagmentation (CUT&Tag) is a novel immunotethering assay, based on Cleavage Under Targets and Release Using Nuclease (CUT&RUN) methods.

In CUT&Tag, a fusion of protein A, protein G, and Tn5 transposase is used to catalyze simultaneous cleavage and sequencing adapter ligation at antibody-bound chromatin. The use of Tn5 in CUT&Tag is a key advance, as this step eliminates the need for chromatin fragmentation as well as expensive library preparation.

CUT&Tag assays display significantly improved signal-to-noise (S/N) vs. ChIP-seq assays, particularly for mapping histone PTMs in ultra-low sample inputs.

Quality data with lower input and sequencing depth requirements

Cuttag Gene

CUTANA™ CUT&Tag generates similar results at a fraction of the cell input and sequencing depth used in ChIP-seq. A representative 300 kb region at the LAMC3 gene is shown for CUT&Tag (orange), CUT&RUN (green) and ChIP-seq (blue) data generated using H3K4me3 and H3K27me3 antibodies (EpiCypher 13-0041 and 13-0030, respectively). Rabbit IgG Negative Control Antibody (EpiCypher 13-0042) and ChIP Input control are shown for comparison (control tracks are scaled to the track with the highest signal in each approach).
