MENLO PARK, Calif. and PARIS, Oct. 06, 2026 (GLOBE NEWSWIRE) -- PacBio (NASDAQ: PACB), developer of the world’s most advanced sequencing technologies, and TychoBio, an AI drug discovery company, today announced a collaboration to generate full-length RNA data that TychoBio will use to train models for RNA therapy design. Under the terms of the agreement, TychoBio plans to use PacBio HiFi sequencing and Kinnex long-read RNA sequencing to generate data from more than 10,000 samples, building large-scale datasets linking the design of steric blocking antisense oligonucleotides (SBOs) to their effects across the transcriptome, with plans to expand the approach to siRNA and other RNA-targeting compounds.

TychoBio will test candidate RNA therapies and use PacBio sequencing to measure how each one changes the transcriptome across multiple cell types. Those results will become training data for models designed to predict which compounds are most likely to work, how long their effects may last, and where unintended effects may occur.

Training models for maximizing on-target efficacy and effect duration of SBOs requires an in-depth understanding of the interaction between SBOs and the cell’s transcriptome. By more fully characterizing the effect of SBOs in various cell lineages, TychoBio will unlock new insights into RNA regulation and SBOs mechanism of action, accelerating the development of safer and more efficient therapeutic designs.

“AI models are only as good as the data they are trained on. To effectively identify new rare disease treatments, we needed the highest quality biological data, which can only be generated using PacBio HiFi sequencing technology,” said Felix Raimundo, founder and CEO of TychoBio. “HiFi long read sequencing lets us see across full-length transcripts, including changes in isoforms and splicing of how the transcriptome is affected in rare diseases and which treatments could modify disease processes.” 

PacBio has partnered across the rare disease community to support the characterization, diagnosis and development of therapeutics to address the global burden of rare disease including through its global HiFiSolves Consortium, the n-Lorem Foundation and EspeRare, the GREGoR Consortium, Care4Rare Canada Consortium, the Genetic Alliance, Genomics England, and many academic collaborations. The company’s Kinnex products, alongside HiFi sequencing, enable screening of thousands of sequences in multiple cell lineages as well as the development of models of both efficacy and toxicity, which are critical to advance potential rare disease therapies out of the laboratory and into patient clinical trials.  

“Our work with TychoBio, like our collaboration with Basecamp Research, highlights the critical value that high-quality sequencing data plays in generating the foundational data that will power biological modeling in the AI ecosystem,” said Mark Van Oene, President and Chief Executive Officer of PacBio. “We believe that this critical work will enable the development of transformative therapies that ultimately improve the lives of patients with rare diseases and their families.” 

The collaboration puts HiFi data directly into the research workflow for designing RNA therapeutics for rare diseases.
