Abstract:
Nanogen, Inc. (Nasdaq:NGEN), developer of advanced diagnostic products, announced today that it has been granted United States Patent No. 7,252,940, titled "Abasic site endonuclease assay" from the U.S. Patent and Trademark Office. The technology described in the patent extends the underlying proprietary real-time PCR technology used in the Company's MGB Alert® products to a new product offering that has been commercialized as research reagents for use in replication validation following genome wide scanning in pharmaceutical and biotechnology industry labs. This technology is also ideal for genetic analysis in multiplex formats of complex genetic diseases.

Nanogen Extends IP Portfolio with Nucleic Acid Detection and Genotyping Technology Patents

SAN DIEGO, CA | Posted on October 1st, 2007

The unique construct of these assay reagents provides researchers with a method for high throughput validation of SNPs (single nucleotide polymorphisms) discovered during genome wide scanning. The goal of many genome wide scanning projects is to identify SNPs associated with particular diseases, such as diabetes or heart failure, in order to identify therapeutic targets or develop diagnostic assays. In order to establish clear disease association, SNPs are validated across large sample populations, often on the order of tens of thousands. This newly patented technology provides the ability to test large numbers of SNPs in parallel across a large number of samples to complete validation in a relatively rapid manner.

Nanogen has also been awarded U.S. Patent No. 7,205,105, "Real-time linear detection probes: sensitive 5'-minor groove binder-containing probes for PCR analysis," related to the probes employed in its MGB Alert® line of reagents. These probes are an important part of the Company's proprietary product offering designed to assist clinical laboratories in developing molecular diagnostic tests that will detect genetic sequences associated with pathogens including those often tested in immunocompromised patients such as cytomegalovirus, Epstein-Barr virus, and enterovirus.
