Single Cell Chromatin Accessibility Solutions

Single Cell Chromatin Accessibility Solutions

In the limited space of the cell nucleus, the majority of the genome is tightly folded, leaving only the part that needs to be transcribed open. Changes in chromatin openness under specific conditions can provide a wealth of information on the regulation of gene expression, pointing the way to the discovery of new sites for binding various proteins, and allow researchers to analyze primary tissues and cells (e.g., islet cells), clinical patient samples, and classify patients and samples based on chromatin openness characteristics. Thus, researchers have a tremendous interest in determining which genomic regions are active in a given cell type.

We offer a single-cell chromatin accessibility solution

CD Genomics can use ATAC-seq (assay for transposase-accessible chromatin with high throughput sequencing) technology to detect open regions of cellular chromatin at the single-cell level with the help of high-throughput sequencing, providing a new solution for the study of regulatory mechanisms at the single-cell genome level.

First DNA probes (which function as transposons) are incorporated into open regions of the genome by enzymatic reactions, and then we can identify these regions by sequencing. In addition to this, CD Genomics offers a solution that includes powerful software analysis and intuitive visualization tools for the analysis of gene regulatory networks in individual cells for single-cell mapping of open regions of cell chromatin.
