Axelios 1 — Roche

Roche's nanopore "sequencing by expansion" (SBX) platform, pitched at a $150 / 30× duplex human genome.

At a glance

  • Vendor / launch date / availability: Roche; revealed at AGBT 2026 (Marco Island, Feb 22–25); pre-orders open post-AGBT; formal commercial launch summer 2026 per GenomeWeb coverage dated Feb 2026.
  • Chemistry / modality: Nanopore sequencing-by-expansion (SBX) — template DNA is enzymatically expanded into a longer, more discriminable polymer before nanopore readout.
  • Throughput (PR): 16 human genomes per run per GenomeWeb / Roche AGBT release (vendor PR — no independent benchmark).
  • Read length: Average duplex ~230–250 bp per GenomeWeb Feb 2026.
  • Accuracy (PR): Q38 duplex per GenomeWeb Feb 2026 (vendor PR — no independent benchmark).
  • List price / cost-per-genome: $750k instrument; $150 per 30× duplex genome; $0.06 per million reads simplex per GenomeWeb Feb 2026.

What's new vs prior generation

Axelios is Roche's first commercial sequencer since exiting 454 — a wholly new modality rather than an incremental upgrade. SBX expands template DNA into a longer reporter polymer that is then read on a nanopore, decoupling read accuracy from native base-by-base translocation speed and giving Roche a route to compete on cost-per-genome rather than read length.

Headline benchmarks

16 human genomes per run, average duplex 230–250 bp, Q38 duplex, $150 / 30× duplex genome (vendor PR — no independent benchmark) — GenomeWeb, Feb 2026.

omicsomics' run-pricing teardown (Mar 2026) argues the $150 headline is conditional on full-run utilization and that effective cost rises sharply at lower batch sizes.

Reception / competitive context

Roche entered AGBT 2026 as the most-watched re-entrant; the $150 genome anchors the lower bound of the AGBT 2026 short-read lineup alongside Element VITARI and Complete DNBSEQ-T7+ (both at $100/genome list). Vilella Part 2 flags the short duplex length (~230–250 bp) as the strategic weakness vs Element / Ultima / Complete on long-insert applications.
