SRU Biosystems Strengthens Intellecutal Property Position Surrounding Label-Free Detection Technology

WOBURN, Mass., April 12 /PRNewswire/ -- SRU Biosystems announced today the receipt of several U.S. patents related to label-free biomolecular detection methods, bringing the Company’s total U.S. portfolio to 16 issued patents.

“SRU has been granted eight additional U.S. patents in the last few months that cover important aspects of our BIND(R) technology, further strengthening our leading position in label-free detection for drug discovery and diagnostics,” stated SRU Biosystems’ President & CEO Owen Dempsey.

Dempsey continued, “SRU’s BIND(R) is a comprehensive solution for customers, combining the benefits of high throughput screening, streamlined and improved assay development, and industry standard formats with breakthrough label-free technology. Working with our customers, we have rapidly expanded the use of the BIND(R) system across nearly the entire spectrum of drug discovery activities, yielding important insights in cell- based, small molecule and protein-protein research. As a review of the titles of these patents indicates, these patents serve to strengthen all aspects of this system, and further exemplify SRU’s position as an innovator.”

The eight awarded patents are: #7,162,125 Optimized grating-based biosensor and substrate combination #7,158,230 Method and apparatus for detecting biomolecular interactions #7,153,702 Label-free methods for performing assays using a colorimetric resonant reflectance optical biosensor #7,148,964 Method and apparatus for detecting biomolecular interactions #7,142,296 Method and apparatus for detecting biomolecular interactions #7,170,599 Method and instrument for detecting biomolecular interactions #7,175,980 Method of making a plastic colorimetric resonant biosensor device with liquid handling capabilities #7,197,198 Biosensor substrate structure for reducing the effect of optical interference About the BIND(R) System

BIND(R) from SRU Biosystems enables label-free detection of biomolecular interactions. The currently commercially available system is comprised of the BIND(R) Reader and 96- or 384-well microplate biosensors. The BIND(R) system takes advantage of a novel optical effect to provide very sensitive measurement of binding on the biosensor surface. The biosensor incorporates a proprietary nanostructured optical grating, which is incorporated in microwell plates in industry standard formats. The BIND(R) system can deliver higher quality assay data as well as improved throughput and associated cost savings.
