What is ATAC-seq?
ATAC-seq stands for Assay for Transposase-Accessible Chromatin with high-throughput sequencing, which is a convenient method to gather genomic information. Specifically, ATAC-seq maps regions of the genome that have open chromatin, that is, regions not occupied by nucleosomes or transcription factors. Open chromatin regions can be linked to epigenetic gene regulation, making ATAC-seq a valuable tool for multiple research fields. ATAC-seq has been used in multiple fields of scientific research ranging from pharmacological studies in immunology, neurobiology, cardiovascular diseases, single-cell chromatin accessibility studies[5,6], and others.
