Cepheid Gets New Patent For Nucleic Acid Amplification, Detection System

NEW YORK, Aug. 11 (GenomeWeb News) - Cepheid announced today the issuance of a patent covering a heating system used in its Smart Cycler and GeneXpert systems for the detection and assessment of genetic targets.


The Sunnyvale, Calf.-based company has exclusively licensed this patent from the University of California for its I-COR, or  Integrated Cooling/heating Optical Reaction system, technology.


The patent, numbered 6,602,473, specifically covers a "silicon-based sleeve type chemical reaction chamber that combines heaters...[and] combines a critical ratio of silicon and non-silicon based materials to provide the thermal properties desired."


"The reaction chamber may be utilized in any chemical reaction system for synthesis or processing of organic, inorganic, or biochemical reactions, such as the polymerase chain reaction (PCR) and/or other DNA reactions, such as the ligase chain reaction, which are examples of a synthetic, thermal-cycling-based reaction," the patent abstract reads. "The reaction chamber may also be used in synthesis instruments, particularly those for DNA amplification and synthesis."


This is the second patent the company has recently licensed for its Itechnology. In June, Cepheid licensed a patent for the optics in the I-COR system.
