True. Single. Molecule. Sequencing.

about us

the story behind

SeqLL was founded in 2013 to bring a new breed of next generation sequencing (NGS) technology, True Single Molecule Sequencing (tSMS), to the research and healthcare communities. By bringing together top-level scientists and engineers with extensive expertise in tSMS technology, SeqLL is uniquely positioned to address gaps left by standard sequencing technologies in RNA transcriptome analysis, specialty DNA analysis & beyond.

Our View

Reczek Liz

Dr. Elizabeth Reczek became CEO in 2015 to guide SeqLL in its transition from an engineering R&D startup to a commercially successful enterprise and responsible partner.

Since the early 2000s, Next Generation Sequencing (NGS) has made tremendous progress, providing previously unprecedented insight into the human genome and making huge amounts of genetic information available to clinicians and researchers.

Initially applied primarily to whole genomes, NGS enabled research has expanded tremendously in the last decade to include research into the regulation of genes, as researchers seek to understand how the static information encoded in our DNA is translated in real time to produce the dynamic changes that occur during development, aging and disease.

RNA is the dominant reservoir of real-time biological information. Understanding disease requires the ability to accurately measure the dynamic changes in these messages to uncover subtle shifts in their levels that indicate changes in metabolic processes or cellular signaling gone awry. The future of diagnosis and personalized treatment of complex disease will require further refinement of our ability to accurately and cost-effectively analyze and quantify RNA. In contrast to an individual’s DNA, which we measure only once to perhaps a few times per lifetime, RNA analysis will be carried out repeatedly throughout an individual’s lifetime to look for subtle changes that indicate the earliest stages of disease, to guide selection of appropriate treatments, follow treatment progress or failure and monitor for unwanted side-effects. This is our vision of the promise of personalized medicine.

This is a lofty goal and one that we cannot accomplish alone. To succeed in redefining medicine as we know it, it is critical that we engage with academic partners in basic research efforts and work to create strong and lasting collaborations with biotechnology and biopharmaceutical companies to bring the results of that research to the market. At SeqLL, we understand that our role in the global personalized medicine initiative is to provide cutting edge sequencing capabilities, through continued innovation in both sequencing technologies and their application, to enable our partners to push back the boundaries of scientific discovery and create novel medicines and diagnostics that will significantly improve patients’ lives.


Dan Jones co-founded SeqLL in 2013 in order to expand the applications of True Single Molecule Sequencing (tSMS) technology. The greater sensitivity, improved accuracy and reduced bias of tSMS makes it ideal for many critical applications such as RNA quantification and analysis of small size genetic material.

Dan, in partnership with the St. Laurent Institute, licensed technology from Helicos in 2013. SeqLL was built to optimize this core technology to focus on specialty sequencing applications, and to improve efficiency, functionality and reliability. Major improvements have been made in design, optical and computing power, and quality.

As a result, SeqLL became the first company to offer direct RNA sequencing, has become a trusted research partner to multiple institutions and is preparing to launch its new True Single Molecule Sequencing system in 2017.

The company continues to value and expand the collaborations that were set up with key opinion leaders in the sequencing field in order to support their efforts, leverage their success and expand the range of applications for tSMS technology. We are proud of the new techniques we have optimized such as DRS (Direct RNA Sequencing) and our RNA-DNA Seq protocols which allow us to provide sequencing without the bias of amplification. This has already resulted in identification of species of bacteria in samples that were otherwise overlooked due to amplification biases. Minimizing the sample preparation steps allows us to not only look at smaller amounts of samples but also a wider range of degraded DNA and RNA.

We look forward to continuing to build on our collaborations with key users in the sequencing field and believe that Single Molecule Sequencing will be the key technology for many short read applications.

As you look for commonalities amongst most of the successful companies, customer service is a common element. There are few companies that were built solely on proprietary products and fewer that remained in a dominant position based only on the technology and products they offer.

In the biotechnology market, customer service requirements are carried to a higher level. Responsive customer service is only the baseline. Strong relationships are built on performance and trust. Many small biotech firms are betting their equity on a vendor’s ability to meet timeline and budgets. At the large pharmaceutical companies, many times, people are betting their careers on the performance of their vendors.

Our management team believes offering a solid product at a reasonable price is only the beginning. It is imperative that all of our employees understand that management does not pay their salaries, our customers do. Therefore when a customer, day or night, needs help, it is our responsibility to do what we can to help them meet their goals. This even more critical with our international customers who are thousands of miles away and many times zones removed. We have to execute on all levels: manufacturing has to make and deliver high quality products on time; our scientists have to stay abreast of new applications and keep our products ahead of the technology curve and just as important we have to maintain a culture where everyone, from our interns to our CEO, understands that there is no compromise in quality or service.
