Stratos Genomics Receives Fundamental Patent on Sequencing by Expansion™ Technology

SEATTLE, WA--(Marketwire - May 25, 2011) - Stratos Genomics Inc today announced it has been granted US Patent 7,939,259 titled "High Throughput Nucleic Acid Sequencing by Expansion." Sequencing by Expansion™ (SBX™) is a method for converting DNA into a more easily-read polymer called an Xpandomer™. Xpandomers encode DNA base sequence information with high signal-to-noise reporters optimally positioned along the polymer chain. SBX is a solution to the intrinsic problem of sequencing native DNA at high-speed and low cost.

The limited signal differentiation of DNA molecules is the overriding factor driving the economics of sequencing today. Existing sequencing technologies overcome the signal-to-noise limitation through intensive sample preparation, complex processing and expensive instrumentation. In contrast, SBX's high signal-to-noise Xpandomers prepared by simple solution-based processing enable ultra-low-cost, single-molecule sequencing on a range of affordable measurement technologies for servicing a full spectrum of genomic applications, including personalized medicine, pathogen identification and environmental monitoring.
