Nanogen Releases Two Products for the Detection of Respiratory Viral Pathogens

    SAN DIEGO, Dec. 12 /PRNewswire-FirstCall/ -- Nanogen, Inc. (Nasdaq:   NGEN),
 developer of advanced diagnostic products, announced today it has expanded its
 molecular reagent product portfolio to include two new products to detect
 sequences for respiratory viral pathogens: a multiplex solid-phase
 hybridization set of reagents that can be employed to develop and validate
 assays for the detection of the sequences of six human respiratory viruses
 prevalent during flu season, and a research-use-only (RUO) real-time PCR probe
 and primer set for the identification of the influenza A and B viruses.
     The NGEN(TM) RVA analyte specific reagent (ASR) product can be used to
 develop and validate assays to detect the sequences of and differentiates
 among influenza A and B, respiratory syncytial virus and parainfluenza 1, 2
 and 3.  Assays validated using NGEN(TM) RVA ASR can be carried out with
 various sample types, including nasal swabs and, once validated by the
 laboratory, can be used as a clinical diagnostic test.  The product was
 developed in cooperation with Prodesse, Inc., a leading supplier of
 molecular-based reagents for infectious disease targets, and is available in
 the United States as an ASR for which analytical and performance
 characteristics are not established.  The product has been CE marked in the
 European Union as an in vitro diagnostic and is available outside the United
 States.
     Additionally, Nanogen has expanded its real-time PCR product group with an
 RUO probe and primer set for the identification of the influenza A and B
 viruses.  The MGB Eclipse(R) Flu A/B RUO product uses the company's
 proprietary MGB(TM) technology to provide melt curve analysis that
 differentiates the two viral strains for each sample.  The new MGB Eclipse(R)
 Flu A/B primer and probe set, along with the recently released Enterovirus and
 hMPV reagents, complement Nanogen's growing MGB Alert(TM) product family of
 ASRs targeting infectious agents, such as herpes viruses and pneumonias.
     Both sets and reagents target a nucleic acid sequence also found in the
 H5N1 strain of the influenza A virus, also known as avian flu.  Laboratories
 interested in screening for avian flu can choose between the real-time PCR
 research reagents or the set of ASRs that can be validated for clinical use.
 Positives could then be sequenced for epidemiological studies.
     "The market for respiratory virus testing is estimated to be over
 $100 million annually.  With the shipment of these new products, Nanogen is
 making a strong play to grab a piece of that market," noted Howard C.
 Birndorf, chairman and chief executive officer of Nanogen.  "Traditionally,
 labs testing for flu have been limited to choosing between simple rapid tests,
 which often lack sensitivity and specificity, or culture-based tests that are
 slow to get results.  Our advanced molecular-based technologies offer clinical
 and research labs additional options.  We believe our products will enable
 changes in laboratory procedures that can influence better prescribing
 practices and improve patient care."
