What does ATAC-seq show?
What is ATAC-Seq? The assay for transposase-accessible chromatin with sequencing (ATAC-Seq) is a popular method for determining chromatin accessibility across the genome. By sequencing regions of open chromatin, ATAC-Seq can help you uncover how chromatin packaging and other factors affect gene expression.
What does the peaks in ATAC-seq tell you?
To do this, we identify areas of the genome that are enriched for aligned reads. These regions are identified and visualized as peaks. Calling peaks therefore represents the identification of regions of concentrated ATAC-seq signal that indicate regions of open chromatin.
What is the difference between ATAC-seq and ChIP-seq?
ATAC-seq is a high-throughput sequencing method for the study of chromatin accessibility. ChIP-Seq combines the selectivity of ChIP with the power of next-generation sequencing (NGS), providing genome-wide profiling of DNA targets for DNA-associated proteins.
How many cells do you need for ATAC-seq?
The hyperactivity of Tn5 transposase makes the ATAC-seq protocol a simple, time-efficient method that requires 500–50,000 cells .
How long are ATAC-seq reads?
The read length prior to any trimming should be a minimum of 45 base pairs. Sequencing may be paired- or single-ended, as long as sequencing type is specified and paired sequences are indicated.
How does single cell ATAC-seq work?

What does open chromatin mean?
Open chromatin regions (OCRs) are special regions of the human genome that can be accessed by DNA regulatory elements. Several studies have reported that a series of OCRs are associated with mechanisms involved in human diseases, such as cancers. Identifying OCRs using ATAC-seq or DNase-seq is often expensive.
How expensive is ATAC-seq?

How much DNA do you need for ATAC-seq?
– Typically, 50,000-100,000 cells yield the best results. As few as 5,000 have been reported to work. The ratio of transposase to cell number is important. We recommend that, if possible, you test different cell numbers and different transposase:cell ratios.
What is single cell ATAC-seq?
Single cell ATAC-seq enables the study of highly heterogeneous samples, identifying unique subpopulations of cell types based on their open chromatin profiles. This could include groups of cells at different developmental stages.
Is ATAC-seq single cell?
Is ATAC-seq stranded?
While naturally occurring transposases have a low level of activity, ATAC-seq employs the mutated hyperactive transposase. In a process called “tagmentation”, Tn5 transposase cleaves and tags double-stranded DNA with sequencing adaptors.
What is 10x ATAC?
The Chromium Single Cell ATAC Solution allows the profiling of cellular chromatin from individual cell nuclei ranging from 500 to 10,000 nuclei per sample and up to 80,000 nuclei per run.
How much does ATAC-seq cost?
What is single cell ATAC?
Chromium Single Cell ATAC (Assay for Transposase Accessible Chromatin) allows you to analyze chromatin accessibility at the single cell level, providing insights into cell types and states, and deeper understanding of gene regulatory mechanisms.
How long does ATAC-seq take?
ATAC-seq requires less material (500–50,000 cells) of tissue/cells and sample-processing time, as opposed to the sequencing of MNase-seq, DNase-seq, and FAIRE-seq. ATAC-seq libraries preparation takes only within 1 day, whereas DNase-seq, MNase-seq, and FAIRE-seq usually require 3–4 days.
