ATAC-Seq

 

ATAC-Seq is a technique used to analyze the functional state of chromatin at the genome-wide level. The assay for transposase-accessible chromatin sequencing identifies regions of open chromatin and efficiently labels them for high-throughput sequencing. Epigenetic regulation includes modulating the transcriptional accessibility of genes through nucleosome positioning and chromatin remodeling. ATAC-Seq has a higher signal-to-noise ratio and lower input requirements than other similar approaches. GENEWIZ Multiomics and Synthesis Solutions from Azenta Life Sciences offers the entire ATAC-Seq workflow, from library preparation to data analysis, and accepts plant tissue as starting material.

Single-cell ATAC-Seq (scATAC-Seq) identifies genome-wide chromatin accessibility at the individual cell-level to uncover how chromatin structure and DNA-binding proteins regulate gene expression in varying states and cellular processes.

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.
