Bio-Rad Launches scATAC-Seq Solution for Early Access Customers
Enables Genome-Wide Open Chromatin Sequencing at the Single-Cell Level

HERCULES, Calif — September 19, 2018 —— Bio-Rad Laboratories, Inc. (NYSE: BIO and BIOb) today announced the early access launch of its scATAC-Seq solution, a single-cell assay for transposase-accessible chromatin using sequencing. The solution harnesses Bio Rad’s ddSEQ Single-Cell Isolator to encapsulate thousands of cell nuclei into nanoliter-sized droplets, in which library preparation for chromatin sequencing occurs. The epigenomics solution enables genome-wide open chromatin sequencing at single-cell resolution.
Researchers studying regulatory biology are increasingly using single-cell gene expression tools such as ATAC-Seq to assess epigenetic differences by analyzing open chromatin regions and nucleosome positioning in regulatory regions and by identifying transcription factors. ATAC-Seq has a two-pronged advantage over other published methods because it does not require separate assays to collect this information, and it does not require millions of cells as starting material. The scATAC-Seq solution has given early access customers the power to study rare cell populations, thereby opening up new applications, such as the ability to study tumor heterogeneity or identify rare cell types in blood.
Bio-Rad’s scATAC-Seq solution enables genome-wide open chromatin sequencing at the single-cell level, leveraging the throughput capabilities of the company’s ddSEQ Single-Cell Isolator to partition thousands of cell nuclei, each into its own nanosized droplet. The solution’s sensitivity is achieved with a hyperactive transposase, which cuts the strands between the nucleosomes into very short fragments for greater resolution.
“The scATAC-Seq solution will specifically allow researchers to ask deeper questions about mechanisms of cell fate, identify the cell types present in heterogeneous tissues, and validate single-cell gene expression data,” said Dan Norton, Senior Product Manager for Bio-Rad’s Digital Biology Group.
In creating the scATAC-Seq solution, Bio-Rad used its expertise in droplets to produce a highly sensitive, high-throughput solution. The ddSEQ Single-Cell Isolator technology enables the processing of thousands of cells at once, in contrast to plate-based systems that can only handle 96 cells per plate. This throughput allows researchers to study immune and cancer cell biology at a deeper, more comprehensive level.
Bio-Rad will present data on how its scATAC-Seq solution enabled the discovery of a large repertoire of epigenomic regulatory elements involved in hematopoiesis and immune responses at the Single Cell Europe Conference in Prague on Friday.
Bio-Rad is sponsoring a Cell Press Webinar on October 10, where an inventor of ATAC-Seq and an early access customer, Jason Buenrostro, PhD, will present his work.
