Next-generation sequencing (NGS)
:quality(90)/)
Next-generation sequencing (NGS) is a powerful tool for tackling unanswered questions. By providing comprehensive and detailed genetic information, today’s NGS solutions are helping researchers uncover the hidden layers of biology that make breakthroughs possible.
As excitement for the promise of NGS grows, Roche has responded to the demand for greater speed, flexibility and accuracy by creating an entirely new class of NGS:
SBX offers ultra-rapid, high-throughput sequencing that is both flexible and scalable.
Designed to accelerate science, it has the potential to transform genomics, empowering researchers to make groundbreaking discoveries that expand our understanding of disease and treatment.
SBX technology will pave the way for the scientific community to address today’s most urgent and complex challenges, while bringing to light the new questions that will shape the future of healthcare.
SBX addresses the limitations of current NGS technologies and provides a space that helps researchers dive deeper, accelerate results and explore experiments that may have been out of reach.
Current on-market nanopore technology works by threading a DNA strand at high speed through the nanopore. A systemic issue with this method, however, is that the DNA’s nucleotide “bases” (adenine, cytosine, guanine and thymine) are so close together that it’s easy to mistake one base for another.
SBX has solved this foundational problem by converting DNA information into an “expanded” synthetic surrogate molecule called an Xpandomer, which is 50 times longer than the target DNA. High signal-to-noise “reporters” that have been encoded with the information of the original DNA sequence are incorporated into the Xpandomers.

As the Xpandomer passes through the nanopore, the reporters provide clear signals with minimal background noise, making it easier to identify the original nucleic acid sequence with high accuracy.
The technology allows hundreds of millions of bases to be accurately detected every second, reducing the time from sample to genome from days to hours, even in a standard laboratory.
SBX has several key features that help scientists overcome challenges with other techniques. Here are some of its unique aspects:
With its immense technological potential and rich future roadmap, SBX will continue to evolve alongside the needs of the NGS market and its customers.

Because it allows scientists to read and understand the order of DNA, NGS has tremendously advanced our understanding of how genes work and interact.
NGS will become increasingly important in deciphering the genetics of complex diseases like cancer, diabetes and neurodegenerative conditions, where hundreds – and even thousands – of genes influence their progression.
Given this, NGS will undoubtedly be at the forefront of many scientific and medical discoveries over the next decade.
With the power of SBX, we can already envision the scientific community potentially finding new ways to:
Boost treatment efficacy, reduce side effects and improve patient outcomes through more personalised medical treatments based on genetic profiles
Ensure early intervention and personalised prevention strategies
Diagnose rare and genetically complex diseases faster and more accurately
Curb the spread of infectious diseases through quick identification of a virus or bacterium
The future is a wide-open space of unlimited possibilities, and innovative diagnostic tools like our SBX technology, which will be a part of a complete sequencing portfolio, are paving the way towards tomorrow’s questions.
This is just the beginning of harnessing the power of space in sequencing. It’s time to let it guide us to the next big breakthroughs in healthcare.
