Nanogen Stock Climbs 10 Percent on Patent News

NEW YORK, Dec. 22 (GenomeWeb News) - Nanogen shares climbed 9.7 percent, or $.25, to reach $2.83 in mid-afternoon trading today following word that the company's Epoch Biosciences unit had been awarded two patents on genetic analysis technologies.


Patent 6,972,339, "Compounds and Methods for Fluorescent Labeling," covers technologies allowing high-throughput synthesis of fluorescently labeled nucleic acid probes and primers. The probes and primers are used in the company's MGB Alert and MGB Eclipse assay formats, Nanogen said.


Patent 6,972,328, "Non-aggregating Non-quenching Oligomers Comprising Nucleotide Analogs, Method of Synthesis and Use Thereof" covers the synthesis and use of pyrazoloprimidine and 7-deazapurine nucleosides as replacements for the natural guanosine nucleoside in diagnostic nucleic acid oligomers.
