Single Cell ATAC Service


Creative Biolabs provides a comprehensive range of customized, high-quality services in single cell ATAC profiling to support various scientific researches worldwide. Analyzing chromatin accessibility at the single cell level can be used to provide insights into gene regulatory mechanisms.


Eukaryotic chromosomes are formed by a series of folding events in nucleosome structures generated by DNA molecules wrapping histone proteins. There are some regions of chromatin that are loosely reformed, called open chromatin or open chromatin regions, where both DNA replication and gene transcription occur. Therefore, obtaining the information will help us understand the regulation of gene expression by open regions, as well as better understanding of biological regulation.

ATAC-seq (Assay for transposase-accessible chromatin with high-throughput sequencing) is a rapid and sensitive epigenetic research technique that uses the Tn5 transposase to cleave open chromatin regions, coupled with sequencing primers (adapter) for high-throughput sequencing (Buenrostro; et al., 2013).

Single Cell ATAC Technology

The 10x Genomics single cell ATAC technology enables the detection of open regions of cellular chromatin at the single cell level. First, the transposase enters the nucleus and preferentially cleaves DNA in the open chromatin regions, while adding sequencing primers to the ends of the DNA fragments; second, in the oil droplets the gel beads with barcodes carry out barcode labeling on the DNA fragments in each cell, and the DNA with barcode labels is used for further library construction; finally, sequencing the library on the Illumina platform, a large number of single cell DNA chromatin open region data can be obtained in one experiment.

Features & Benefits

1. High throughput

About 500-10,000 nuclei can be obtained per channel efficiently; for high throughput platform, we can run 8 samples (80,000 nuclei per run) in one experiment.

2. High resolution

The chromatin accessibility information can be obtained at a single-cell nucleus level.

3. High capture efficiency

The capture efficiency of nuclei can reach up to 65% per sample.

4. Ultra-low contamination

The number of mitochondrial DNA reads is less than 2%.

5. More comprehensive information

We can get information on all open chromatin regions, not limited to a single transcription factor.

6. One-stop service

We can provide one-stop service from sample processing to data visualization; or provide customized analysis procedures with the most up-to-date technical solutions.
