An optimized ATAC-seq protocol for genome-wide mapping of active regulatory elements in primary mouse cortical neurons

ATAC-seq is a versatile, adaptable, and widely adopted technique for mapping open chromatin regions. However, some biological systems, such as primary neurons, present unique challenges to its application. Conventional ATAC-seq would require the dissociation of the primary neurons after plating but dissociating them leads to rapid cell death and major changes in cell state, affecting ATAC-seq results. We have developed this modified ATAC-seq protocol to address this challenge for primary neurons, providing a high-quality and high-resolution accessible chromatin profile. For complete details on the use and execution of this protocol, please refer to Maor-Nof et al. (2021). Keywords: Genetics; Genomics; Molecular Biology; Neuroscience; Sequencing.
