AutoCUT&Tag: streamlined genome-wide profiling of chromatin proteins on a liquid handling robot
 
Resource Report
Resource Website
Derek Janssens, Steven Henikoff DOI:10.17504/protocols.io.bgztjx6n protocols.io news, Human Cell Atlas Method Development Community The CUT&Tag method is based on antibody tethering of the Tn5 transposase to profile the genome-wide occupancy of DNA-binding proteins, histone modifications and chromatin modifying proteins in situ starting from relatively low cell numbers (1-100K cells). Activation of tethered transposase integrates library adapters at the sites of bound chromatin factors. By taking advantage of protocol modifications that enable Tn5 release and PCR in the same sample reaction chamber, we adapted CUT&Tag to an automated 96 well format. We provide programs and equipment specifications for performing AutoCUT&Tag on a Beckman Coulter Biomek FX liquid handling robot equipped for magnetic separation and temperature control, but in principle the method could be easily translated to other liquid handling units. Using this automated protocol a single operator is able to generate up to 96 CUT&Tag libraries in a single day that are ready to be pooled and sequenced.

When ligated to both ends of DNA, they add 64bp and 124bp respectively. This makes huge difference when you do beads based cleaning up.What is this protocol?This protocol is based on library preparation manual of “NEBNext® Ultra™ II DNA Library Prep Kit for Illumina”, NEB E7645, and is specifically modified to make libraries from small DNA fragments (25-150bp).

Marlon Stoeckius, Peter Smibert DOI:10.17504/protocols.io.ngzdbx6 Human Cell Atlas Method Development Community This collection contains our main protocols for performing CITE-seq and Cell Hashing, specifically on Drop-seq or 10x Genomics single cell 3′ v2 chemistry. CITE-seq: Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq) is a multimodal single cell phenotyping method developed in the Technology Innovation lab at the New York Genome Center in collaboration with the Satija lab.CITE-seq uses DNA-barcoded antibodies to convert detection of proteins into a quantitative, sequenceable readout.  Antibody-bound oligos act as synthetic transcripts that are captured during most large-scale oligodT-based scRNA-seq library preparation protocols (e.g. 10x Genomics, Drop-seq, ddSeq).This allows for immunophenotyping of cells with a potentially limitless number of markers and unbiased transcriptome analysis using existing single-cell sequencing approaches.Cell Hashing:Sample multiplexing and super-loading on single cell RNA-sequencing platforms.Cell Hashing uses a series of oligo-tagged antibodies against ubiquitously expressed surface proteins with different barcodes to uniquely label cells from distinct samples, which can be subsequently pooled in one scRNA-seq run. By sequencing these tags alongside the cellular transcriptome, we can assign each cell to its sample of origin, and robustly identify doublets originating from multiple samples.

CUT&RUN: Targeted in situ genome-wide profiling with high efficiency for low cell numbers
 
Resource Report
Resource Website
Steven Henikoff DOI:10.17504/protocols.io.n6wdhfe Human Cell Atlas Method Development Community We previously described a novel alternative to Chromatin Immunoprecipitation, Cleavage Under Targets & Release Using Nuclease (CUT&RUN), in which unfixed permeabilized cells are incubated with antibody, followed by binding of a Protein A-Micrococcal Nuclease (pA/MNase) fusion protein (1). Upon activation of tethered MNase, the bound complex is excised and released into the supernatant for DNA extraction and sequencing. Here we introduce four enhancements to CUT&RUN: 1) a hybrid Protein A-Protein G-MNase construct that expands antibody compatibility and simplifies purification; 2) a modified digestion protocol that prevents premature release of the nuclease-bound complex; 3) a calibration strategy based on carry-over ofE. coliDNA introduced with the fusion protein; and 4) a novel peak-calling strategy customized for the low-background profiles obtained using CUT&RUN. These new features, coupled with the previously described low-cost, high efficiency, high reproducibility and high-throughput capability of CUT&RUN make it the method of choice for routine epigenomic profiling.

Single-cell mapping of lineage and identity via CellTagging
 
Resource Report

Brent A. Biddy, Wenjun Kong, Kenji Kamimoto, Chuner Guo, Sarah Waye, Tao Sun, Samantha Morris DOI:10.17504/protocols.io.yxifxke Human Cell Atlas Method Development Community, Morris Lab Single-cell technologies are offering unprecedented insight into complex biology, revealing the behavior of rare cell populations that are typically masked in bulk population analyses. One current limitation of single-cell approaches is that lineage relationships are lost as a result of cell processing, restricting interpretations of the data collected. Elegant computational approaches have been developed in an effort to infer these missing observations, but it remains a challenge to reconstruct true reprogramming trajectories using these tools. Although sophisticated lineage tracing solutions to connect cell history with fate are emerging, these protocols are either not compatible with high-throughput scRNA-seq, or require genome editing strategies that are not readily deployed in some systems. Here, our protocol describes a single-cell resolution clonal tracking approach, ‘CellTagging’, based on combinatorial cell indexing, permitting the parallel capture of lineage information and cell identity. CellTagging integrates with high-throughput single-cell RNA-sequencing, where iterative rounds of cell labeling enable the construction of multi-level lineage trees. This straightforward lentiviral-labeling approach can be applied to an array of cell biological applications to simultaneously profile lineage and identity, at single-cell resolution.

Bench top CUT&Tag
 
Resource Report
Resource Website
Hatice Kaya-Okur, Steven Henikoff DOI:10.17504/protocols.io.bcuhiwt6 Human Cell Atlas Method Development Community Here we describe a bench top protocol for 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 one day. We have demonstrated the utility of CUT&Tag by profiling histone modifications, RNA Polymerase II and transcription factors on low cell numbers and single cells. Version 3 includes an optional light formaldehyde treatment of cells or nuclei prior to antibody addition. Light fixation reduces the tendency of cells or nuclei to clump, which can also be reduced for fixed and unfixed nuclei by omitting digitonin from all steps.
