Inventor Mark Kokoris on Roche’s New Sequencing by Expansion
The biggest story in sequencing this year lives up to the hype. Mark Kokoris, head of SBX sequencing at Roche and inventor of the technology, joins Mendelspod to talk about how Sequencing by Expansion (SBX) works and why it may redefine the limits of genomics.* 0:00 A long journey inspired by PCR* 7:20 What is sequencing by expansion?* 14:00 On scale and accuracy* 19:40 Multi-omics vision?* 24:40 What will be the killer app?* 30:00 Biggest challenge for launchKokoris recounts the long path from co-founding Stratos Genomics in 2007 to Roche’s acquisition in 2020, when his team’s “wildly ambitious chemistry” finally found its match in Genia’s high-density nanopore platform. “Our approach to efficiently sequencing DNA,” he explains, “is to not sequence DNA. We rescale the problem—expand the molecule about 50-fold—so we can read it with much higher signal-to-noise.”The result is astonishing speed. Working with the Broad Institute and Boston Children’s Hospital, SBX delivered whole-genome results in under four hours, with the sequencing step itself taking only about 15 minutes. Kokoris attributes the achievement to a confluence of chemistry and compute.SBX’s duplex mode achieves Illumina-level accuracy (F1 > 99.8 %) while maintaining single-molecule simplicity. Its tunable flexibility lets small labs run a handful of samples in hours or large centers run thousands per day. Kokoris describes it as a technology built on impatience and rule-breaking, designed to give scientists options they’ve never had.Looking ahead to the 2026 research-use launch, he’s characteristically bold:“For me, success means SBX becoming the new standard in sequencing. Innovation can’t stop—it has to keep evolving, because biology is complex and we’ve got a lot more to do.” This is a public episode.

From Brewing Sake to Brewing Science: Takara Bio’s Bold New Chapter with CSO Andrew Farmer
What company began as a sake manufacturer over a century ago and went on to launch the world’s first single-cell kit in 2011? It’s Takara Bio—and their story is far from finished.In this episode, we talk with Dr. Andrew Farmer, Chief Scientific Officer and Head of R&D at Takara Bio USA, about the company’s remarkable evolution from a Japanese enzyme maker to a global innovator in single-cell and spatial biology. Farmer recalls, “We go way, way back to being a sake manufacturer a hundred years ago. And it’s through that business—realizing that sake is basically fermentation—that we could use that to do other interesting things in biology.”* 0:00 Began as a sake manufacturer over 100 years ago* 5:25 First kit for single-cell sequencing* 11:10 Bought Curio Bioscience to bring in spatial omics* 15:00 Returning to the level of the cell* 26:40 The new “T-cell sponge”He describes how Takara Bio introduced the first commercial single-cell reagent kit long before the current explosion of single-cell technologies: “The first single-cell reagent kit on the market was actually from us. That was in 2011, and even the Fluidigm C1 system was driven by our chemistry.”The conversation then moves through Takara’s acquisition of Curio Bioscience, adding the Trekker and Seeker spatial platforms, which—remarkably—require no specialized instruments. Farmer explains how this simplicity could democratize access to spatial data and accelerate multiomic studies in cancer and drug discovery.And for an ending twist, he introduces the “T-cell Sponge,” a porous hydrogel matrix that activates and transduces T cells in a single step—an innovation recently named one of The Scientist’s Top Innovations of 2025.

How Pathologists Can Lead in Precision Medicine with David Braxton
When should a genetic test be ordered—and who decides? It’s a question we are constantly asking on the program. Dr. David Braxton, Chief of Molecular Pathology at Hoag Memorial Hospital in Southern California, has built a system where the answer is simple: the pathologist decides. At Hoag, reflex testing protocols automatically trigger genomic tests when certain cancers appear under the microscope—embedding precision medicine directly into the biopsy workflow.* 0:00 How did you become an advocate for precision medicine?* 5:50 What triggers the ordering of a genetic test?* 12:00 Using national lab vs in-house* 19:03 Which areas show most progress?* 24:32 A fan of early cancer testing?* 29:42 How digitized is your lab?* 42:45 Moonshot? Treat CHIP“We developed standardized operating procedures where if a pathologist sees certain types of cancers in certain states, they automatically order the genomic testing,” Braxton explains. “It’s all very formalized. We call it pathologist-initiated reflex testing—and it gets results into the medical record before the oncologist even sees the patient.”Braxton talks about making genomic profiling routine in a community setting, the barriers that still slow precision medicine—education, reimbursement, regulation—and how digital pathology and AI are reshaping what pathologists can see and do. “The real value of digital pathology and AI,” he says, “isn’t necessarily helping pathologists do their jobs quicker or better—it’s going beyond what the human eye can see.”Braxton offers a pragmatic, hopeful look at how community hospitals can lead the next phase of precision oncology. We discuss the increasingly used MRD testing and get Braxton’s thought’s on early cancer detection tests. In the end, he shares his “moonshot:” using molecular diagnostics to detect clonal hematopoiesis, a precursor state that silently increases risk for leukemia, heart disease, and other inflammatory conditions. “If you want to talk about the role of diagnostics in decreasing chronic conditions like heart attacks and cancer,” he says, “this is the moonshot—catching that silent killer early with molecular techniques.” This is a public episode.

From DNA to Proteins: Illumina Makes Its Proteomics Play - with Krishna Morampudi
Illumina has just made a bold move into proteomics.In this episode of Mendelspod, Krishna Morampudi, Associate Director for Product Management at Illumina, joins Theral to talk about the company’s recent definitive agreement to acquire SomaLogic and the new launch of Illumina Protein Prep, their new end-to-end proteomics solution.0:00 On the acquisition of SomaLogic4:30 Scoop: Illuminated Protein Prep just launched8:00 Competitive edge14:15 The larger multi-omics visionIllumina’s new product can screen for 9,500 proteins using SomaLogic’s SOMAmer technology, with sequencing on NovaSeq and data processed through Illumina’s existing connected analysis platforms. According to Morampudi, the integration with Illumina’s NGS workflows gives researchers a competitive edge and lowers the barrier to proteomics adoption.The product has already launched with early access customers, including large biobank studies such as UK Biobank through partnerships with Decode Genetics. Krishna notes that “the motivation to buy the company was really coming from working with those early access customers.”With a vision to make large-scale quantitative proteomics standard in discovery research, Illumina is betting that SomaLogic’s scalable, high-throughput tech can eventually outpace long-established competitors.“We’re starting with 9,500 proteins with lower CVs than Olink. Our ability to scale faster to the entire native proteome gives us a real advantage,” Morampudi says.In the final segment, Morampudi connects the proteomics launch with Illumina’s broader multi-omics vision and outlines the potential for new biomarker discovery, PQTL analysis, and phenotypic insights.
