CUT&Tag-IT^® Service

Cleavage Under Targets and Tagmentation (CUT&Tag) is a method to investigate genomic localization of histone modifications that reveals interactions between proteins and DNA or identifies DNA binding sites for proteins of interest.

CUT&Tag utilizes an antibody-based enzyme tethering strategy to target specific histone modifications or proteins to reveal chromatin-binding information that is specific to those sites or proteins of interest.

CUT&Tag is based on the same principles as ChIP-Seq, but with several changes to the protocol that are advantageous in certain situations. Instead of the sonication of fixed chromatin and immunoprecipitation steps performed in ChIP-Seq protocols, in CUT&Tag, unfixed cells are bound to concanavalin A beads and the antibody incubation is performed with cells in their native state. Directly following antibody binding, the chromatin is digested and NGS libraries are prepared in a single step by tagmentation using the protein A-Tn5 (pA-Tn5) transposase enzyme that has been pre-loaded with sequencing adapters.

Our Tn5 Transposase assisted chromatin tagmentation methods are covered by these patents: US9938524, US10689643B2, EP2783001B1, EP2999784B1.

What are the Advantages of Using Active Motif’s CUT&Tag-IT^® Service?

CUT&Tag can be used to identify genome-wide histone modification or transcription factor profiling using a fraction of starting material that is recommended for ChIP-Seq. Having the ability to use less starting material allows for the profiling of histone modifications and transcription factor binding studies in sample types that due to sample quantities were not suitable for ChIP-Seq.

CUT&Tag also has the advantage of low background signal such that a lower sequencing depth can be used resulting in high-quality data at a fraction of the cost of ChIP-Seq.

With our end-to-end CUT&Tag-IT^® Service, you don’t need to worry about protocol optimization or testing multiple antibodies to try to find one that works because we take care of all of that for you. There’s also no need to learn bioinformatics because analysis of the next-generation sequencing data and explanation of the results are included standard.

Figure 1. Correlation between ChIP-Seq and CUT&Tag data in K562 cell line.
Chromatin landscapes from human K562 cells are shown across a 500 kb segment of the human genome region (Chr5: 138,850-139,350) for H3K27me3 (blue), H3K4me3 (green), and H3K27ac (red) showing high concordance of CUT&Tag signals from 100,000 cells compared with ENCODE ChIP-Seq data from at least one million cells. Antibodies used in the CUT&Tag assays for the following targets were: H3K27me3: cat. no 39155, H3K4me3: cat. no. 39159, 39917, H3K27ac: cat. no. 39133.

Chromatin landscapes from human A549 cells are shown across a 350 kb segment of the human genome region (chr8:67,812-68,162) for H3K27me3 (blue), H3K4me3 (green), and H3K27ac (red), H3K4me1 (light blue) showing high concordance of CUT&Tag signals from 100,000 cells compared with ENCODE ChIP-Seq data from at least one million cells. Antibodies used in the CUT&Tag assays for the following targets were: H3K27me3: cat. no. 39155, H3K4me3: cat. no. 39159, H3K27ac: cat. no. 39133, H3K4me1: cat. no. 39238.
