QIAGEN Launches Novel Assay Technology for miRNA Targets

Innovative Assay Technology for miRNA Adds a Unique Solution to QIAGEN's Leading miRNA Portfolio


VENLO, The Netherlands, May 7, 2007 (PRIME NEWSWIRE) -- QIAGEN N.V. (Nasdaq:QGEN) (Frankfurt:QIA), the world's leading provider of sample and assay technologies for research in life sciences, applied testing and molecular diagnostics, today introduced a pioneering technology which creates a new dimension of capabilities for assays targeting microRNAs (miRNAs). miRNA-related research in academia, pharma and molecular diagnostics can be considered one of the most rapidly evolving fields in today's life sciences.

miRNAs are a newly discovered class of RNA molecules which have been found to play a significant role in the regulation of gene expression. Recent discoveries indicate that miRNAs can correlate with cancer and other diseases, sparking significant interest in today's life science and molecular diagnostics research. Despite the significant importance of this new class of RNA molecules, current methods for the isolation, identification and quantification of the presence of miRNA in biological samples are often cumbersome and imprecise.

QIAGEN today unveiled a unique solution which allows for the sensitive, specific and simultaneous detection and quantification of hundreds of different miRNAs as well as other RNAs (e.g. mRNA). The newly launched miScript product line incorporates a proprietary technology which for the first time enables researchers to identify multiple miRNAs from one single cDNA reaction in a given biological sample. cDNA is a synthesized copy of the RNA which is widely used for PCR-based target detection in molecular biology, biomedical and pharmaceutical research. The features offered by QIAGEN's proprietary miScript assay technology can equate to substantial time savings while allowing tremendous sensitivity and specificity.

"The new miRNA system marks a great step forward in miRNA research," said Dr. Constanze Kindler, Senior Product Manager at QIAGEN. "So far, researchers had to create a new copy of the DNA every time they wanted to detect a miRNA molecule. This often leads to inconsistent results and a waste of precious samples, such as cancer and tissue cells. miScript simply makes miRNA detection faster, more economical and convenient," Dr. Kindler added.

The new system expands QIAGEN's already broad portfolio of sample and assay technologies targeting the rapidly expanding field of miRNA and demonstrates the company's well established capabilities and leadership in the field of sample and assay technologies.

Together with QIAGEN's other sample and assay technologies products for miRNA such as with QIAGEN's miRNeasy kits, the new QIAGEN miScript system forms an integrated and comprehensive solution for the isolation and detection of miRNAs in hundreds of assays, which are available for the human, mouse and rat genome and which can easily be ordered via QIAGEN's web portal GeneGlobe.

About RNAi and miRNA:

RNAi is a mechanism which allows to turn "on" and "off" genes by regulating the formation (or expression) of proteins. Last year's Nobel Prize in Medicine was awarded to Craig C. Mello and Andrew Z. Fire for research in the field of RNAi. Like its synthetic cousin molecule siRNA, the naturally found small microRNA, which is not bigger than 24 base pairs, is assumed to play a key role in this process. miRNAs correlate with various cancers and diseases and seem to be formed in DNA regions called introns, which until very recently were considered to have no specific function. Today, researchers believe that these regions are subject to accelerated genetic variation and help explain what genetically separates human beings from much less complex organisms, which are endowed with a similar number of genes.

Since microRNA have been discovered very recently, the market is still small, but it is growing exponentially and can be considered one of the most rapidly evolving fields in today's life sciences. Estimates show that the global RNAi market could grow annually up to 30 percent, and that it could reach US$330 million in worldwide revenues by 2010. QIAGEN believes it is the market and technology leader in RNAi products used in many fields, including in pharmaceutical research.
