Illumina announced a roadmap of hardware and chemistry improvements for its NovaSeq X platform to boost read output, speed and accuracy—promising new 5 billion‑read flow cells, a 600‑cycle kit for longer reads, and future Q50/Q70 quality kits for high‑sensitivity clinical applications. The vendor positioned the updates as a response to intensifying competition in high‑throughput sequencing. Rivals are pressing: Ultima Genomics unveiled the UG200 series and Solaris 2.0 workflow that remove emulsion PCR, reduce footprint and cut runtimes, pitching lower list prices and higher genomes‑per‑footprint productivity. The announcements signal escalating platform competition that could reshape procurement and application choices for large genomic centers and clinical labs.
