ROCHE ROLLS OUT NEW DNA 'SEQUENCING-BY-EXPANSION' APPROACH

Summary from the TLDR newsletter

Sequencing-by-expansion is a new proprietary method that pulls apart DNA molecules and amplifies the signal of each individual base, allowing scientists to avoid the time requirements of cycle-based sequencing as well as the comparable difficulties in distinguishing true signals among the noise. The technology is still in development and not yet commercially available, but it could one day be suitable for whole genome and exome sequencing as well as parsing RNA. The science behind the technology represents a significant breakthrough that addresses the limitations of existing sequencing solutions. It has the potential to revolutionize the use of sequencing in research and healthcare.
