Assay for Transposase-Accessible Chromatin using sequencing (ATAC-seq)

ATAC-seq is a scientific technique used to identify open, accessible regions of DNA within cells. It utilizes an enzyme called transposase that inserts small sequencing tags into areas where the DNA is loosely packed and accessible for gene activity. By sequencing these tags, researchers can map which parts of the genome are active and accessible for gene regulation, providing insight into how cells function and respond to different conditions. This method helps scientists understand complex biological processes, such as development, disease, and gene expression, by revealing the landscape of accessible chromatin across the genome.
