Fluorescent in situ sequencing (FISSEQ) of RNA for gene expression profiling in intact cells and tissues Resource Report Resource Website |
Je Hyuk Lee, Evan R. Daugharthy, Jonathan Scheiman, Reza Kalhor, Thomas C. Ferrante, Richard Terry, Brian M. Turczyk, Joyce L. Yang, Ho Suk Lee, John Aach, Kun Zhang, and George M. Church | DOI:10.17504/protocols.io.mgsc3we | Human Cell Atlas Method Development Community | RNA sequencing measures the quantitative change in gene expression over the whole transcriptome, but it lacks spatial context. On the other hand, in situ hybridization provides the location of gene expression, but only for a small number of genes. Here we detail a protocol for genome-wide profiling of gene expression in situ in fixed cells and tissues, in which RNA is converted into cross-linked cDNA amplicons and sequenced manually on a confocal microscope. Unlike traditional RNA-seq our method enriches for context-specific transcripts over house-keeping and/or structural RNA, and it preserves the tissue architecture for RNA localization studies. Our protocol is written for researchers experienced in cell microscopy with minimal computing skills. Library construction and sequencing can be completed within 14 d, with image analysis requiring an additional 2 d. | Wyss Institute, Harvard Medical School, Boston, MA, Harvard Medical School, Boston, MA, Harvard Medical School, Boston, MA, Department of Genetics, Harvard Medical School, Boston, MA, Wyss Institute, Harvard Medical School, Boston, MA, Wyss Institute, Harvard Medical School, Boston, MA, Wyss Institute, Harvard Medical School, Boston, MA, Department of Genetics, Harvard Medical School, Boston, MA, Department of Electrical and Computer Engineering, UC San Diego, CA, Department of Genetics, Harvard Medical School, Boston, MA, Department of Bioengineering, UC San Diego, La Jolla, CA, Harvard Medical School, Boston, MA | https://www.nature.com/articles/nprot.2014.191 | 1 | 2018 | Je Hyuk Lee, Evan R.

RNA Imaging with MERFISH - Design of Oligonucleotide Probes Resource Report Resource Website |
Jeffrey R. Moffitt, Xiaowei Zhuang | DOI:10.17504/protocols.io.menc3de | Human Cell Atlas Method Development Community, Neurodegeneration Method Development Community | The first step in any MERFISH experiment is the design of the oligonucleotide probes that will be used to label individual RNA species. In our current implementation of MERFISH, each oligonucleotide encoding probe consists of three basic components as illustrated in Figure 2. The first region is a 30-nt targeting region that is complementary to a portion of the sequence of the RNA to which it is designed to bind. The second region is a set of sequences that are called readout sequences, which were designed to be complementary and hence only bind to MERFISH readout probes and not other nucleic acid in the cell. Finally, the third region is a set of priming regions used in the construction of these probes, which will be discussed in detail in Probe Construction. In addition to the nucleotide sequences for each of these components, a codebook —the specific set of binary barcodes that will be used and their association with different RNA species of interest—must also be designed. In this section, we provide protocols to design these sequences and to build a codebook. Example code to perform these steps can be found at http://zhuang.harvard.edu/merfish/ . | Harvard University, Cambridge, Massachusetts, Harvard University, Cambridge, Massachusetts | https://www.ncbi.nlm.nih.gov/pubmed/27241748 | 1 | 2018 | Jeffrey R.

CITE-seq and Cell Hashing Resource Report Resource Website |
Marlon Stoeckius, Peter Smibert | DOI:10.17504/protocols.io.nhqdb5w | Human Cell Atlas Method Development Community | This protocol is for performing CITE-seq and Cell Hashing in parallel. 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. | New York Genome Center Technology Innovation Lab, New York Genome Center Technology Innovation Lab | https://cite-seq.com/protocol/ | 1 | 2018 | Marlon Stoeckius, Peter Smibert 2018.

Preparation of Single-Cell RNA-Seq Libraries for Next Generation Sequencing Resource Report Resource Website |
John J. Trombetta, David Gennert, Diana Lu, Rahul Satija, Alex K. Shalek, Aviv Regev | DOI:10.17504/protocols.io.pbhdij6 | Human Cell Atlas Method Development Community | For the past several decades, due to technical limitations, the field of transcriptomics has focused on population-level measurements that can mask significant differences between individual cells. With the advent of single-cell RNA-Seq, it is now possible to profile the responses of individual cells at unprecedented depth and thereby uncover, transcriptome-wide, the heterogeneity that exists within these populations. Here, we describe a method that merges several important technologies to produce, in high-throughput, single-cell RNA-Seq libraries. Complementary DNA (cDNA) is made from full-length mRNA transcripts using a reverse transcriptase that has terminal transferase activity. This, when combined with a second “template-switch” primer, allows for cDNAs to be constructed that have two universal priming sequences. Following preamplification from these common sequences, Nextera XT is used to prepare a pool of 96 uniquely indexed samples ready for Illumina sequencing. | Broad Institute of MIT and Harvard, 7 Cambridge Center, Cambridge, MA 02142, USA,, Broad Institute of MIT and Harvard, 7 Cambridge Center, Cambridge, MA 02142, USA,, Broad Institute of MIT and Harvard, 7 Cambridge Center, Cambridge, MA 02142, USA,, Broad Institute of MIT and Harvard, 7 Cambridge Center, Cambridge, MA 02142, USA,, Department of Chemistry and Chemical Biology and Department of Physics, Harvard University, 12 Oxford Street, Cambridge, MA 02138, USA, Howard Hughes Medical Institute, Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02140, USA | https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4338574/#R8 | 1 | 2018 | John J.

CUT&Tag-direct with CUTAC Resource Report Resource Website |
Steven Henikoff, Jorja Henikoff, Hatice Kaya-Okur, Kami Ahmad | DOI:10.17504/protocols.io.bmbfk2jn | Human Cell Atlas Method Development Community | CUT&Tag@direct uses a modification of Bench-top CUT&Tag which includes incubation in 0.1% SDS post-tagmentation for quantitative release of targeted fragments, followed directly by PCR with Triton-X100 to neutralize the SDS. This protocol is performed in single PCR tubes from nuclei to sequencing-ready libraries and should be suitable for high throughput. The protocol has been enhanced by the addition of hyperaccessibility mapping by Cleavage Under Targeted Accessible Chromatin (CUTAC), where H3K4me2 CUT&Tag samples are tagmented in low salt for mapping of the hyperaccessible site close to the H3K4me2-labeled nucleosomes.In situ tethering for CUT&Tag chromatin profiling.a) The steps in CUT&Tag. Added antibody (green) binds to the target chromatin protein (blue) between nucleosomes (gray ovals) in the genome, and the excess is washed away. A second antibody (orange) is added and enhances tethering of pA-Tn5 transposome (gray boxes) at antibody-bound sites. After washing away excess transposome, addition of Mg++ activates the transposome and integrates adapters (red) at chromatin protein binding sites. After DNA purification genomic fragments with adapters at both ends are enriched by PCR. b) CUT&Tag is performed on a solid support. Unfixed cells or nuclei (blue) are permeabilized and mixed with antibody to a target chromatin protein. After addition and binding of cells to Concanavalin A-coated magnetic beads (M), all further steps are performed in the same reaction tube with magnetic capture between washes and incubations, including pA-Tn5 tethering, integration, and DNA purification. | Henikoff S, Henikoff JG, Kaya-Okur HS, Ahmad K, Efficient chromatin accessibility mapping in situ by nucleosome-tethered tagmentation. eLife doi: 10.7554/eLife.63274 | Fred Hutchinson Cancer Research Center, Fred Hutchinson Cancer Research Center, Fred Hutchinson Cancer Research Center, Fred Hutchinson Cancer Research Center | https://doi.org/10.7554/eLife.63274 | 2 | 2020 | Steven Henikoff, Jorja Henikoff, Hatice Kaya-Okur, Kami Ahmad 2020.

'Frankenstein’ protocol for nuclei isolation from FRESH and FROZEN tissue for snRNA-Seq (10x Genomics Platform) Resource Report Resource Website |
Luciano Martelotto | DOI:10.17504/protocols.io.bq27myhn | Human Cell Atlas Method Development Community, Single Cell Core, Harvard Medical School | This protocol is the result of the combination of various nuclei isolation protocols for single cell RNA-seq experiments using droplet-based methods, hence the name Frankenstein. Developed to prepare nuclei isolates from small sample sizes (as little as a grain of rice), this protocol uses FACS to identify cell subpopulations based on ploidy (e.g. tumor versus stroma), to ensure that nuclei suspensions are not clumped, and to remove any debris, especially ambient RNA, to help reduce background. The reference protocols can be found in the following papers: Hu, et al., Habib, et al. (2016), Habib, et al. (2017), Lake, et al., and Lacar, et al.This protocol has been validated in the Single-Cell Innovation Lab (UMCCR) and other labs worldwide for single nuclei experiments using 10x Genomics technologies.The protocol has been demonstrated to work successfully with fresh, snap/flash frozen, cryopreserved cells, and cell lines, as well as various solid cancers: pancreas, pheochromocytomas, paragangliomas, breast cancer, lymphoma, xenografts and other samples types.Cardiomyocytes can be really difficult to prepare but we have successfully prepare this.
