QIAGEN Significantly Expands its Portfolio of Licenses to real-time PCR

Two New Licenses Added to Technology Portfolio targeting Molecular Diagnostics

VENLO, The Netherlands, February 12, 2007 - QIAGEN N.V. (Nasdaq: QGEN, Frankfurt, Prime Standard: QIA), the worldwide leading provider of sample and assay technologies for research in life sciences, applied testing and molecular diagnostics today announced that it has acquired licenses from Roche, as well as from Ortho Clinical Diagnostics. These two license agreements significantly expand QIAGEN's rights to real-time polymerase chain reaction (PCR) for use in In Vitro Diagnostics (IVD). Financial terms were not disclosed.

The two separate and independent agreements provide QIAGEN with access to a major portfolio of additional patent and marketing rights, which were not covered by the original licensing agreements with Roche. Through these agreements QIAGEN is broadening its technology portfolio to assay technologies and diagnostic tests using almost any basic PCR patent and real-time PCR patent rights related to reagents and methods for practicing PCR and real-time PCR for IVD.

Through the license extension agreement with Roche QIAGEN is now licensed under all real- time polymerase chain reaction (PCR) patents and pending patent applications owned or controlled by Roche Diagnostics, a division of F. Hoffmann-La Roche Ltd, Basel, Switzerland. The agreement with Roche includes, but is not limited to, additional enzyme patent rights further PCR improvement patent rights and pathogen specific patent rights.

In addition, QIAGEN obtained a license from Ortho Clinical Diagnostics to patents related to a taq-polymerase antibody mediated method used to initiate PCR. This is often referred to as a "Hot-Start" technology because it accelerates the activation of PCR enzymes and thereby accelerates the start of the PCR process. The license gives QIAGEN rights in the fields of in research, applied testing and IVD.

"Real-time PCR is the most widely accepted technology for the quantitative amplification and detection of nucleic acids and has become a strong standard in life sciences, applied testing and molecular diagnostics." said Achim Ribbe, QIAGEN's Executive Director Corporate Business Development. "The acquisition of these new patent licensing rights, together with our own PCR related intellectual property rights, creates for QIAGEN what is probably the broadest license portfolio for the basic patent rights related to reagents and methods for practicing PCR and real-time PCR and related products. These additional licenses bring to QIAGEN valuable assets which expand QIAGEN's technology leadership in sample and assay technologies for the life sciences, applied testing and molecular diagnostics."

About PCR:

The polymerase chain reaction, or PCR, is today considered one of the most widely used technologies in molecular biology. Invented by Kary Mullis in 1983, he received a Nobel Prize for his discoveries in 1993. Today, PCR is the most frequently used technique in many areas of basic and applied research in molecular biology, biochemistry, and medicine, and is used in many applications, including detection and quantification of DNA and RNA targets in research, applied testing and molecular diagnostics.

PCR is a method for amplification of specific nucleic acid sequences from a complex mixture of nucleic acids. The DNA in a sample is separated into single strands through heating, and each strand acts as a template for enzymatic extension of the missing complementary strand. The beginning and end of the amplified segment are defined through the addition of short, highly specific DNA molecules, known as primers. This replication cycle is repeated many times, leading to exponential amplification of individual segments of DNA.

In real-time PCR, a specific sequence of DNA is amplified and quantified. The amplified sequence binds to a fluorescence which is measured. This allows calculation of the original amount of the sequence. Real-time PCR takes place in a real-time thermal cycler, which provides the appropriate temperatures for the different steps of each amplification cycle and also measures fluorescence.
