Single-Cell Sequencing

What Is Single-Cell Sequencing?

Single cell sequencing allows us to isolate the transcriptome or DNA of each individual cell, enabling cell type identification and deconvolution of a heterogeneous population of cells.

Researchers use single-cell RNA sequencing to examine the small complexities of each region of the transcriptome. Single-cell DNA sequencing can identify mutations and chromatin accessibility in individual cells.

Single cell sequencing recognizes that every cell is as different as the person it belongs to. By isolating the components of an individual cell, researchers are better able to understand how and why that cell responds to stimuli and direct diagnosis, drug discovery, and treatment.

Why Is Single Cell Sequencing Important?

Traditional RNA sequencing relies on extraction of RNA from tissue, a heterogeneous mix of cell types. RNA extraction from cell culture or sorted cell types include cells at different stages of their development. Sequencing results yield an average gene expression across all cell types and stages. A dying cell’s transcriptome influences data just as much as a live, differentiating cell.

Bulk RNA sequencing does not yield a transcriptomic profile representative of any individual cell in that sample. Single cell sequencing allows us to isolate the transcriptome of each individual cell, enabling cell type identification and deconvolution of a heterogeneous population of cells.

What Can You Do?

Cancer Research

Tumors are a mix of healthy and cancerous cells, as well as potential immune infiltrate. Differentiating transcriptomic profiles of healthy versus cancerous cells can yield potential targets for treatment therapies, in hopes of developing treatment options which will leave healthy tissues unaffected. Similarly, identification of immune cell populations provide insight into innate immune response, presenting additional pathways for treatment.

Neuroscience

The nervous system is a highly complex system composed of a variety of cell types. Single cell sequencing allows for the identification of the cellular composition of brain and CNS tissues, including cellular subtypes. Over 3,000 different cell types have been identified in the human brain, emphasizing the delicate balance that cellular composition plays in human development. Transcriptional changes can contribute to neurodegenerative and neurological diseases.

Immunology

An organism’s immune system relies on a wide variety of cell types. However, the specificity of the adaptive immune system comes from genetic mutations and recombination events, meaning each lymphocyte can have a unique transcriptomic profile. Single cell sequencing can isolate an individual T or B cell and identify its VDJ regions. This provides a more complete picture of an organism’s immune response, guiding treatments and understanding of conditions from autoimmunity to aging.

Single-Cell Sequencing Workflows from 10x Genomics^®
10x technologies provide a diverse portfolio of single-cell options.
Microfluidics encapsulate an individual cell along with a Gel Bead, coated in uniquely barcoded oligo-dT primers for mRNA capture.
This process creates full length cDNA suitable for long read sequencing.
Capture up to 20,000 cells/sample with high throughput assays.

Standard gene expression capture. Use gene expression levels to identify cell subtypes and cell trajectories. Compatible with full length cDNA sequencing.

Gene expression capture, compatible with immune profiling for human and mouse TCR and BCR enriched sequencing and targeted enrichment.

Compatible with 3' and 5' gene expression assays.

Combine multiple pre-labeled samples into a single lane.

Chromatin accessibility from a single nucleus, assessing its availability for interaction with proteins, namely transcription factors. Determine the prevalence of subpopulations and their overall impact on a heterogeneous cell sample – a critical area of regulatory pathway discovery.

3' gene expression plus ATAC from the same nucleus. A good choice for solving research and discovery problems at a systems biology level. Determine what gene expression is occurring and how the structure of that DNA may regulate that expression.

Psomagen was the first 10x Certified Service Provider for scATACSeq in the US and the second worldwide.

Probe-based capture from fixed or FFPE human and mouse cells or nuclei.

Combinatorial barcoding uniquely tags mRNA within a cell. Cells are fixed and permeabilized, enabling long term storage and collection for longitudinal studies. Oligo-dT and random RNA capture possible.

Three sizes of kits enable capture of:

12 samples, up to 10,000 total cells
48 samples, up to 100,000 total cells
96 samples, up to 1,000,000 total cells

Recent advancements in methodologies support a variety of projects:

3' gene expression
Human TCR enrichment
CRISPR screening
Targeted gene capture

High-throughput, instrument free emulsion capture uses core templated particles coated with a barcoded primer to capture mRNA. This technology is compatible with TotalSeq-A for multiplexing many samples in a single reaction.

3' gene expression protocols are available in three sizes:

T2 — up to 2,000 cells
T20 — up to 20,000 cells
T100 — up to 100,000 cells

Currently available for run-only projects at Psomagen, with more capabilities on the way.

One-cell-per-well method sorts each cell into a separate well for unique barcoding. A great choice for whole genome studies, because the proprietary primary-template directed amplification (PTA) yields a more accurate representation of the genome.

Provides more efficient RNA capture within a cell, reducing the need for high cell numbers.

Two sample type options available:

ResolveDNA
ResolveOME
