Assay for Transposase-Accessible Chromatin with High-Throughput Sequencing (ATAC-Seq) Protocol for Zebrafish Embryos

Assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq) is a useful method to map genome-wide chromatin accessibility and nucleosome positioning. Genome-wide sequencing is performed utilizing adapter sequences inserted by a prokaryotic transposase, Tn5, into the accessible regions of chromatin. Here we describe the use of ATAC-seq in the zebrafish embryo and thereby the applicability of this approach in whole vertebrate embryos.
