CUTANA™ assays vastly outperform ChIP-Seq

When compared with ChIP-seq, CUTANA™ assays have lower sequencing requirements, improved Signal-to-Noise, and reduced assay time.

How do CUTANA™ assays work?
CUTANA™ assays use a proprietary immunotethering approach similar to Chromatin ImmunoCleavage (ChIC)1 and Cleavage Under Targets and Release Using Nuclease (CUT&RUN)2,3 methods. This approach can be used to map histone post-translational modifications (PTMs) and chromatin interactors with high sensitivity and resolution.

This approach leverages a factor specific antibody to tether a fusion of protein A, protein G and micrococcal nuclease (pAG-MNase) to genomic binding sites in intact cells, which is then activated by the addition of calcium to cleave DNA. The pAG-MNase enzyme is the first reagent in the CUTANA™ product line and is available now.

Overview of the approach
Cells (or nuclei) are immobilized on lectin-coated magnetic beads, permeabilized, and incubated with an antibody to a chromatin target (e.g. histone PTM or chromatin / DNA binding protein). Next, pAG-MNase is added and activated via Ca2+. The clipped chromatin fragments diffuse out, followed by DNA purification and next-generation sequencing. CUTANA™ assays vastly outperform those using chromatin immunoprecipitation, the current gold-standard genomic mapping assay.

Data Analysis

CUTANA™ assays save 5-10x in sequencing requirements

CUTANA™ assays generate superior quality data compared to ChIP-seq using as little as 3 million sequencing reads.

Comparing data generated from standard ChIP-seq methods and sequencing depth (black) to CUTANA (blue). H3K27me3 and H3K4me3 ChIP-Seq data was sourced from ENCODE. Negative control data (yellow) was generated using a Rabbit IgG antibody in CUTANA. Each dataset of CUTANA was acquired using 0.5 million cells.

Available To Order Now


Recombinantly produced in E. coli, CUTANA™ pAG-MNase for ChIC/CUT&RUN Workflows is a fusion of Proteins A and G to Micrococcal Nuclease. This construct is useful in performing Chromatin Immunocleavage (ChIC)1 and Cleavage Under Targets and Release Using Nuclease (CUT&RUN)2,3. CUTANA™ pAG-MNase contains a C-terminal 6xHis epitope tag.
