Single-Cell ATAC-Seq (scATAC-Seq) Service
End-to-end service to identify open chromatin regions at single-cell resolution
Single Cell ATAC-Seq (scATAC) is based on transposase-mediated insertion of sequencing primers into open chromatin regions. This assay, like traditional ATAC-Seq, provides profiles of open and accessible regions of chromatin that are indicative of active regulatory regions at single cell resolution.
Our scATAC-Seq service enables examination of genome-wide chromatin accessibility of thousands of cells in parallel, allowing examination of subpopulations of cells within a heterogenous population that would otherwise be lost in standard ATAC-Seq.
What are the advantages of using scATAC-Seq?
scATAC-Seq can be used to identify cell subpopulations with different chromatin accessibility profiles within complex samples, eliminating the need for isolation strategies like FACS or magnetic sorting that could alter the biology due to sample manipulation. For example:
- Identifying cancer stem cells or infiltrating macrophages within a tumor sample
- Identifying novel cell subpopulations that are responsible for response to drug treatments (i.e. responders vs. resistant cells)
- Identifying subpopulations of cells with variations in chromatin accessibility that can provide insight into developmental trajectories (i.e. brain development, T-helper cell development, B-cell differentiation)
What is single cell ATAC-Seq?
How is scATAC-Seq different from bulk ATAC-Seq?
Are there any QC steps included in Active Motif’s scATAC-Seq service?
- After the generation of scATAC-Seq libraries, each library is assessed for quality and proper size using TapeStation or equivalent and quantity is confirmed using qPCR
- Shallow sequencing (5-10M reads) and analysis to assess quality metrics (FRIP and number of peaks) prior to deeper sequencing
- After full-scale sequencing, there are several numerical and graphical quality metrics assessed during bioinformatics analysis
