High throughput joint profiling of chromatin accessibility and protein levels in single cells [PBMC stimulation]

Default Boolean Operator: Terms in a search string will be connected by the AND operator, EXAMPLE: searching genomic melanoma will produce the same results as genomic AND melanoma .
AND, OR, NOT: Combine terms in a search with the boolean operators AND (to add specificity), OR (to broaden), or NOT (to eliminate a term). Operators must be capitalized (all other search terms are not case-sensitive).
Wild Card: Add wild card symbols * (open-ended) and ? (single character) to truncate terms. EXAMPLE: searching gen* shows results for 'gene', 'genetic', 'genomic, etc. Searching gene? returns results for 'gene' or 'genes' but not for 'genome'.
Phrase Searching: Enclose search in quotation marks "keyword or search term" to search for an exact phrase. EXAMPLE: "transcription factors" returns results for records where transcription is immediately followed by the word factors .
Diacritics: Words containing diacritics translate those characters to non-diacritic form. EXAMPLE: massague returns results for Massague&#769 .
Filter by: Located on the homepage (left panel), use filters to search for records or narrow the search. From search results page, filters can be removed by clicking on the term at the top of the page.

Description: Summary from GEO:

"Recent technological advances have enabled massively parallel single-cell Assay for Transposase Accessible Chromatin by sequencing (scATAC-seq) to simultaneously profile the epigenomic landscape in thousands of individual cells. scATAC-seq methods sample genomic DNA accessible to transposases, but have not previously been combined with measurement of protein levels. Here, we present ATAC with Select Antigen Profiling by sequencing, ASAP-seq, a tool to simultaneously profile accessible chromatin and protein levels in thousands of single cells, pairing sparse scATAC data with robust detection of hundreds of cell surface and intracellular protein markers, and optionally, enriched mtDNA coverage for lineage tracing (mtscATAC-seq) with minimal impact on ATAC-seq data quality. ASAP-seq makes use of a novel bridging approach to utilize existing commercially available antibody:oligo conjugates developed for CITE-seq and related technologies. We demonstrate the utility of ASAP-seq in the context of hematopoietic differentiation, cell surface marker dynamics following peripheral blood mononuclear cell stimulation, and as a combinatorial decoder of multiplexed perturbations in primary T cells."

Overall design from GEO:

"Control and stimulated with aCD3/CD28 PBMC samples were stained with a 227-antibody panel and used to apply CITE-seq and ASAP-seq to simultaneously measure changes in protein, mRNA levels, and chromatin accessibility."
