NEW YORK (GenomeWeb) – Pacific Biosciences has launched a new single-molecule sequencing system that offers higher throughput and costs about half the price of its RS II system, the company said.

PacBio developed the Sequel as part of its collaboration with Roche to develop a clinical-grade sequencing system for diagnostic purposes. That collaboration is ongoing, and the launch of Sequel marks another step toward the final goal.
