Nanogen Releases Enterovirus Reagent Employing Newly Patented Hybridization Technology

    SAN DIEGO, June 15 /PRNewswire-FirstCall/ -- Nanogen, Inc. (Nasdaq:  
 NGEN), developer of advanced diagnostic products, announced today that it
 has expanded its product portfolio to include the MGB Alert(TM) ENV
 real-time PCR reagent, designed to detect sequences associated with
 enteroviruses. Prevalent in summer and fall, enterovirus infections cause a
 wide spectrum of diseases and are the most common cause of aseptic
 meningitis.
     "According to the Centers for Disease Control, enteroviruses cause an
 estimated 10 to 15 million symptomatic cases a year in the United States,"
 said Howard C. Birndorf, Nanogen chairman and chief executive officer.
 "Enterovirus testing constitutes a segment of the infectious disease
 molecular diagnostics market, which is expected to reach $2.3 billion by
 2010."
     "Detection of viral infections by real-time PCR is typically faster,
 more sensitive and more specific than through other methods," said
 Birndorf, "and should help reduce the healthcare costs associated with
 enteroviral infections." Aseptic meningitis cases account for tens of
 thousands of hospitalizations every year.
     George E. Buck, chief of microbiology at Norton Healthcare in
 Louisville, KY, finds the MGB Alert ENV product to be "very sensitive and
 easy to use. Physicians at our hospital rely on our results to help them
 diagnose these infections."
     Nanogen's MGB Alert Enterovirus analyte specific reagent (ASR), like
 all MGB Alert products, utilizes novel detection chemistry claimed in U.S.
 Patent 7,045,610, issued to Nanogen May 16. The '610 patent, "Modified
 Oligonucleotides for Mismatch Discrimination," claims the use of modified
 bases to improved hybridization-based diagnostic assays.
     The patented chemistry is employed in most of the company's ASRs and
 research products, enabling laboratories to develop multiple assays with
 universal parameters, which increases the efficiency and throughput of
 clinical testing. The super bases (Super A(TM), Super T(TM), Super G(TM)
 and Super N(TM)) and MGB technology described in '610 allow the use of
 shorter probes with increased sensitivity to mismatches, which have proved
 essential for detecting short conserved sequences of enteroviruses as well
 as other pathogens.
     "Specifically, '610 allows Nanogen to deliver real-time PCR probe and
 primer designs for targets that would be otherwise intractable," said
 Birndorf.
