Epigenetic regulation includes modulating the transcriptional accessibility of genes through nucleosome positioning and chromatin remodeling. Assay for transposase-accessible chromatin sequencing (ATAC-Seq) identifies regions of open chromatin and efficiently labels them for high-throughput sequencing. ATAC-Seq has a higher signal-to-noise ratio and lower input requirements than other similar approaches. GENEWIZ now offers the entire ATAC-Seq workflow, from library preparation to data analysis. Now accepting plant tissue!

To identify genome-wide chromatin accessibility at the individual cell-level and uncover how chromatin structure and DNA-binding proteins regulate gene expression in varying states and cellular processes, learn more about GENEWIZ’s single-cell ATAC-Seq.

ATAC-Seq Overview

Assay for transposase-accessible chromatin sequencing (ATAC-Seq) employs a hyperactive form of Tn5 transposase to identify regions of open chromatin, which are important for global epigenetic control of gene expression. Tn5 simultaneously cleaves and adds adapters to nucleosome-free regions of DNA, priming them for sequencing.
