Quidel Announces Worldwide, Exclusive License for Novel DNA Microarray (MChip) for Global Influenza Surveillance

MCHIP Developed by University of Colorado and Validated by CDC

SAN DIEGO--(BUSINESS WIRE)--Dec. 19, 2006--Quidel Corporation (NASDAQ:QDEL), a leading provider of rapid point-of-care (POC) diagnostic tests, today announced an exclusive, worldwide license to the MChip microarray-based influenza detection technology developed by scientists at the University of Colorado (CU) in close collaboration with the U.S. Centers for Disease Control and Prevention (CDC).

"We are extremely pleased with this licensing agreement with the University of Colorado and the CDC, as it strategically positions Quidel Corporation with an important technology and tool in the molecular diagnostic field," commented Caren Mason, president and CEO of Quidel Corporation. "With the acquisition of this validated technology, Quidel looks ahead to expand its product range and reinforce its market leadership in rapid point-of-care influenza diagnostics," added Mason.

Quidel's intent is to develop and market molecular-based diagnostic tests featuring the MChip for use in pandemic surveillance, as a tool for the clinical laboratory and at the point-of-care in the physician office laboratory.

The MChip offers several advantages over current molecular-based arrays for the detection of influenza viruses, including the recently disclosed FluChip developed by the same research team at the University of Colorado at Boulder and the CDC. While the majority of molecular-based arrays use sequences from three influenza genes -- hemagglutinin (HA), neuraminidase (NA) and matrix (M) -- the MChip exclusively exploits sequences from the matrix genes. Unlike HA and NA, which mutate constantly, the M gene segment is more conserved. A diagnostic test based on this relatively stable gene segment should be more robust because it will continue to provide accurate results even as the HA and NA genes mutate and will require less frequent reconfiguration. In addition, current molecular tests provide only information about the type of virus present in a single sample (i.e., Influenza type A or Influenza type B). The MChip offers the advantage of simultaneously typing and subtyping the flu virus in a single procedure (for example, Influenza type A, subtype H5N1), avoiding the need for additional subtyping of the virus.

As reported by CU, the MChip has been validated in collaboration with the CDC by testing H5N1 samples collected over a three-year period from people and animals around the world and to date has correctly identified 24 different H5N1 flu strains at 97% sensitivity and 100% specificity, with no reported false positives.

In a November 14, 2006 NIH press release, Dr. Nancy Cox, Director of the influenza division of the U.S. Centers for Disease Control and Prevention, stated the following: "This new technology, once manufactured and distributed, could have the potential to revolutionize the way laboratories test for influenza. The MChip could enable more scientists and physicians, possibly even those working in remote places, to more quickly test for H5N1 and to accurately identify the specific strain and its features."

Dr. Kathy Rowlen, Project Leader of the CU discovery team commented: "We are delighted that Quidel has licensed the MChip technology. We see Quidel as the ideal company to bring this technology to health care providers and surveillance personnel around the world due to their established leadership in point-of-care diagnostics and reputation for high quality products."
