Low-input ATAC&mRNA-seq protocol for simultaneous profiling of chromatin accessibility and gene expression

Abstract

Summary: We present a simple, fast, and robust protocol (low-input ATAC&mRNA-seq) to simultaneously generate ATAC-seq and mRNA-seq libraries from the same cells in limited cell numbers by coupling a simplified ATAC procedure using whole cells with a novel mRNA-seq approach that features a seamless on-bead process including direct mRNA isolation from the cell lysate, solid-phase cDNA synthesis, and direct tagmentation of mRNA/cDNA hybrids for library preparation. It enables dual-omics profiling from limited material when joint epigenome and transcriptome analyses are needed.For complete details on the use and execution of this protocol, please refer to Li et al. (2021).
