Single Cell Sequencing

BCL’s single cell sequencing service offerings deliver the reproducibility and quality needed for small or large scale single cell projects. Automated processes yield a level of data consistency and quality difficult to achieve in lower-throughput laboratories with manual sample preparation methods.

Single Cell Sequencing with
Broad Clinical Labs

Single cell sequencing services available from BCL include 10x Gene Expression (3′ or 5′), 10x Genomics Multiome (ATAC-Seq + gene expression), and SmartSeq2.

10x Single Cell
Gene Expression
(3' or 5')

The 10x Single Cell Gene Expression (3' or 5') (GEX) assay enables transcriptional profiling at the single cell level across thousands of cells, providing insight into how cellular heterogeneity contributes to a biological system.

Customers can target regions at the 3' and/or 5' end of transcripts. Both 3' and 5' assay versions can be supplemented with feature barcoding to enable selective targeting of cell surface proteins. The 5' assay can also be paired with a T or B cell enrichment to further investigate immune cells.

Samples are sequenced using a workflow that enables customization of the depth of sequencing targeted for each sample, based on customers' unique cell types and quantities.

10x Genomics Single Cell
Multiome (ATAC-Seq +
Gene Expression)

10x Genomics Single Cell Multiome (ATAC-Seq + Gene Expression) services at BCL utilize a kit developed by 10x Genomics that combines ATAC-Seq (assay for transposase accessible chromatin) and gene expression, simultaneously generating transcriptomic and epigenetic information from a single source sample. This service enables customers to access cell states and regulatory mechanisms more deeply than with single cell expression data alone.

To date, BCL has successfully generated Multiome data for nuclei derived from blood, tumor tissue, and fresh frozen brain tissue.

SmartSeq2
Single Cell
Sequencing

SmartSeq2 Single Cell Sequencing accurately profiles gene expression in single cells and is ideal for applications such as profiling gene expression in stem cell differentiation, organ development, tumor progression, and characterization of cell population responses to environmental signals and conditions.

Unlike most single cell methods, SmartSeq2 is compatible with frozen/archival sample types, and the sample preparation method results in full-length transcript capture, as opposed to 3' tags.
