Parse Biosciences Launches Whole Transcriptome
Kit to Dramatically Scale Single Cell Sequencing

Now commercially available, the Whole Transcriptome Kit enables researchers in neuroscience, immunology, oncology, as well as other areas of scientific study, to achieve industry-leading detail on cell types and subtypes

Seattle, WA, February 18, 2021

Parse Biosciences., a company providing researchers with scalable and flexible single cell sequencing solutions, today announced the launch of their Single Cell Whole Transcriptome Kit. The kit, which was previously available only through Parse’s early access program, is now generally available to all researchers in North America.


The Whole Transcriptome Kit from Parse Biosciences contains everything needed to run a single cell experiment with 100,000 cells across 48 samples. Previously, single cell sequencing solutions demanded that researchers invest in expensive lab equipment to get started. Now, with the launch of Parse Bioscience’s Whole Transcriptome Kit, researchers have a reliable and scalable, end-to-end single cell sequencing technology that utilizes only basic lab equipment.


“For too long, labs have been held back by technologies that not only compromise on data quality, but which also don’t scale to match researchers’ ambitions,” said Alex Rosenberg, co-founder and CEO of Parse. “Through our Whole Transcriptome Kit, we support researchers who are taking on some of the most challenging problems in biology — spanning neuroscience, immunology, and beyond. We provide them with a technology that is more scalable and offers higher resolution than anything else on the market, including droplet-based solutions.”


Since their pioneering paper on SPLiT-seq published in Science in 2018, Parse Biosciences has continued to refine their technology. The Whole Transcriptome Kit marks a tremendous improvement from the proof-of-concept introduced in the company’s paper, with improved sensitivity and industry-leading data resolution.


Key features of the Single Cell Whole Transcriptome Kit include: 

Increased scalability

  • Accommodation of up to 48 unique biological samples and up to 100,000 cells or nuclei with a single kit.

Flexible workflow

  • Separation of the sample extraction from downstream library preparation steps empowers researchers to run fixed samples collected on different dates together in a single experiment.

  • Long-term storage (up to 6 months) of fixed samples — with no impact on gene expression or the number of transcripts detected per cell. 

  • Full compatibility with both cells and nuclei gives researchers the choice on how to prepare their samples 

Increased Resolution

  • A lower doublet rate than anything else on the market. Researchers can trust the data is true single cell data.

  • Increased sensitivity enables high transcript detection including cells with low RNA content such as PBMCs.

Out-of-the-box capabilities

  • No custom instrument means researchers can get started quickly with no capital costs. Through split-pool combinatorial barcoding, researchers can bypass the need for expensive and complicated microfluidic instruments. 

  • The Parse Biosciences pipeline is an out-of-the-box software tool that you can run locally to go straight from sequencing files to processed data. The pipeline produces interactive outputs that make it possible to browse gene expression across different biological samples and cell populations. 

Through their early access program, Parse Biosciences’ Whole Transcriptome Kit has already been used in 50 labs across the country, providing researchers with improved resolution and throughput in their experiments.

“Combinatorial barcoding is going to transform the way people do single cell sequencing. It’s simple, elegant, and incredibly scalable,” said Lawrence T. Reiter, PhD and Professor of Neurology at The University of Tennessee Health Science Center. “With Parse Biosciences’ Whole Transcriptome Kit, I’ve been able to finally reveal the neuronal and glial characteristics of our dental pulp stem cell neuron cultures.”

With the launch of the Whole Transcriptome Kit, Parse Biosciences is also making available three datasets encompassing cell lines, brain nuclei, and immune cells. Through these datasets, researchers can see firsthand how the Whole Transcriptome Kit enables highly sensitive gene detection across a wide variety of sample types.

“With these datasets, our goal is to give researchers the ability to explore the capabilities of this technology before they ever bring it into their own labs,” said Charlie Roco, co-founder and CTO of Parse Biosciences. “This is really a whole new level of data, and we want to open it up and use it to inspire researchers. Our goal is that as researchers begin to manipulate our datasets, they realize the extent that single cell sequencing can support them in their research.”

“We have spent the last three years developing a product that more scientists could actually use,” said Charlie Roco, co-founder and CTO of Parse Biosciences. “Our kits are now operating at a higher level than anything else we’ve seen on the market and our company has evolved beyond our original SPLiT-seq method. We wanted our brand to reflect that.”


Researchers in both the pharmaceutical industry and academia have increasingly leveraged single cell technologies to drive discovery. Single cell RNA sequencing continues to transform research across every field of biology and medicine, and the pace of adoption shows no sign of slowing down, with the global single-cell analysis market expected to continue growing at a CAGR of 18% through 2027. 


Through single cell sequencing, researchers are able to interrogate biological systems through a new lens, leading to insights that were previously obscured without single cell resolution. To date, however, researchers are limited in their options. While other single cell sequencing solutions on the market require expensive lab equipment, Parse Biosciences has developed a technique that enables single cell sequencing with only basic lab equipment. By removing the most prohibitive barrier to access, the company’s kits help bring single cell sequencing to virtually every research lab around the world.  


“From the sheer scalability of their technology, to the entirely unique flexibility that their single cell sequencing kits provides to researchers, Parse Biosciences is creating a new standard for the single cell market,” said Rob Carlson, managing director at Bioeconomy Capital. “We’re excited to back this emerging leader of the industry and support their continued expansion to serve labs all over the world.”


Parse Biosciences enables researchers to scale their single-cell sequencing and achieve more flexible workflows. By using combinatorial cDNA barcoding within cells themselves, Parse Biosciences’s technology allows researchers to eliminate the need for complex and expensive microfluidic instruments. Additionally, the company’s technology enables samples to be fixed, frozen and stored, allowing researchers to separate out the sample extraction from downstream library preparation steps. This capability empowers researchers to run fixed samples collected on different dates together in a single experiment, providing greater control over sample handling and reducing handling errors.
