WebbIn ATAC-Seq, genomic DNA is exposed to Tn5, a highly active transposase. Tn5 simultaneously fragments DNA, preferentially inserts into open chromatin sites, and adds sequencing primers (a process known as tagmentation). The sequenced DNA identifies the open chromatin and data analysis can provide insight into gene regulation. Webb11 aug. 2024 · ATAC-seq is a highly efficient approach to studying chromatin accessibility. Nevertheless, the activity of a hyperactive Tn5 transposase is essential to ATAC-seq. This transposase works through tagmentation, which fragments the genome while inserting the sequencing adapter.
