CUT&Tag for efficient epigenomic profiling of small samples and single cells (807 single cells)

ABSTRACT: Many chromatin features play critical roles in regulating gene expression. A complete understanding of gene regulation will require the mapping of specific chromatin features in small samples of cells at high resolution. Here we describe Cleavage Under Targets and Tagmentation (CUT&Tag), an enzyme-tethering strategy that provides efficient high-resolution sequencing libraries for profiling diverse chromatin components. In CUT&Tag, a chromatin protein is bound in situ by a specific antibody, which then tethers a proteinA-Tn5 transposase fusion protein. Activation of the transposase efficiently generates fragment libraries with high resolution and exceptionally low background. All steps from live cells to sequencing-ready libraries can be performed in a single tube on the benchtop or a microwell in a high-throughput pipeline, and the entire procedure can be performed in one day. We demonstrate the utility of CUT&Tag by profiling histone modifications, RNA Polymerase II and transcription factors on low cell numbers and single cells.

Low-cost high-resolution chromatin profiling with CUT&Tag

Project description:We recently introduced CUT&Tag, an epigenomic profiling strategy in which antibodies are bound to chromatin proteins in situ in permeabilized nuclei, and then used to tether the cut-and-paste transposase Tn5. Activation of the transposase simultaneously cleaves DNA and adds DNA sequencing adapters (“tagmentation”) for paired-end DNA sequencing. Here, we introduce a streamlined CUT&Tag protocol that suppresses exposure artifacts to ensure high-fidelity mapping of the antibody-targeted protein and improves signal-to-noise over current chromatin profiling methods. Streamlined CUT&Tag can be performed in a single PCR tube from cells to amplified libraries, providing low-cost high-resolution genome-wide chromatin maps. By simplifying library preparation, CUT&Tag requires less than a day at the bench from live cells to sequencing-ready barcoded libraries. Because of low background levels, barcoded and pooled CUT&Tag libraries can be sequenced for ~$25 per sample, enabling routine genome-wide profiling of chromatin proteins and modifications that requires no special skills or equipment.

CUT&Tag2for1: a modified method for simultaneous profiling of the accessible and silenced regulome in single cells

Project description:Cleavage Under Targets & Tagmentation (CUT&Tag) is an antibody-directed transposase-tethering chromatin profiling strategy for small samples and single cells. Previously, we showed that activation of tethered Tn5 transposase under low-salt conditions using antibodies that target promoters and enhancers produces high-resolution genome-wide chromatin accessibility maps. Here we show that low-salt CUT&Tag using a mixture of an antibody to the initiation form of RNA Polymerase II (Pol2 Serine-5 phosphate) and an antibody to repressive Polycomb domains (H3K27me3) followed by computational signal deconvolution produces efficient high-resolution maps of both the active and repressive regulomes. We have extended this CUT&Tag2for1 method to single cells using a novel deconvolution approach, thus producing high-quality multifactorial single-cell chromatin maps with a workflow that is identical to that for standard single-cell CUT&Tag. The ability to seamlessly map both the active and repressive regulatory elements in single cells provides a complete regulome profiling strategy suitable for high-throughput single-cell platforms.

Scalable single-cell profiling of chromatin modifications with sciCUT&Tag

Project description:Cleavage Under Targets & Tagmentation (CUT&Tag) is an antibody-directed in situ chromatin profiling strategy that is rapidly replacing precipitation-based methods. The efficiency of the method enabled chromatin profiling in single cells but is limited by the numbers of cells that can be profiled. Here, we describe a combinatorial barcoding strategy for CUT&Tag that harnesses a nanowell dispenser for simple, high-resolution high-throughput single-cell chromatin profiling. We describe a pipeline for single-cell indexed CUT&Tag (sciCUT&Tag) that uses SNPs to facilitate doublet-cell removal and minimize batch effects. We illustrate the optimized protocol by analysis of mouse and human cell lines, as well as human peripheral blood mononuclear cells. We have also used sciCUT&Tag for simultaneous profiling of multiple chromatin epitopes in single cells. The reduced cost, improved resolution and scalability of sciCUT&Tag make it an attractive platform to profile chromatin features in single cells.

Efficient transcription-coupled chromatin accessibility mapping in situ

Project description:Chromatin accessibility mapping is a powerful approach to identify potential regulatory elements. In the popular ATAC-seq method, Tn5 transposase inserts sequencing adapters into accessible DNA (‘tagmentation’). CUT&Tag is a tagmentation-based epigenomic profiling method in which antibody tethering of Tn5 to a chromatin epitope of interest profiles specific chromatin features in small samples and single cells. Here we show that by simply modifying the tagmentation conditions for histone H3K4me2/3 CUT&Tag, antibody-tethered tagmentation of accessible DNA sites is redirected to produce accessible DNA maps that are indistinguishable from the best ATAC-seq maps. Thus, DNA accessibility maps can be produced in parallel with CUT&Tag maps of other epitopes with all steps from nuclei to amplified sequencing-ready libraries performed in single PCR tubes in the laboratory or on a home workbench. As H3K4 methylation is produced by transcription at promoters and enhancers, our method identifies transcription-coupled accessible regulatory sites.

Identification of chromatin states during zebrafish gastrulation using CUT&RUN and CUT&Tag

Project description:Here we describe successful implementation of CUT&Tag for profiling protein-DNA interactions in zebrafish embryos. We optimized CUT&Tag protocol to generate high resolution maps of enrichment for the histone variant H2A.Z during zebrafish development. We were able to establish dynamics of H2A.Z genomic patterning from shield stage to 24hpf embryos. Our work demonstrates the power of combining CUT&Tag with the strengths of the zebrafish system to better understand the changing embryonic chromatin landscape and its roles in shaping development.
