Sigma-Aldrich (SIAL) Announces Agreement to Manufactured and Commercialize Zip Nucleic Acid

November 3, 2009 9:37 AM EST

Sigma-Aldrich (NASDAQ: SIAL) today announced a worldwide licensing agreement with Polyplus-transfection (Strasbourg, France) to manufacture and commercialize Zip Nucleic Acid (ZNA*) oligonucleotides, a new technology that provides solutions for increased affinity for nucleic acids. Under the terms of the license, Sigma-Aldrich has rights to manufacture and commercialize ZNA oligonucleotides for all research applications. Sigma-Aldrich is the first company to offer ZNA as custom DNA and RNA oligonucleotides to the life science community.

ZNA are oligonucleotides with attached cationic units. They offer significant value for a variety of applications in research and diagnostics applications. Research applications include PCR probes, PCR primers, in-vitro micro RNA detection and inhibition and siRNA. The addition of cationic residues to oligonucleotides increases their sensitivity and their ability to detect mutations, while remaining both easy to design and cost effective. ZNA also offers an increased affinity for nucleic acids without losing selectivity, improving performance in hybridization techniques.

"Sigma-Aldrich offers the largest portfolio of modifications and labels for oligonucleotides. We consider ZNA an important addition to our portfolio. The increased performances seen for ZNA oligonucleotides offers advantages for our customers, and we look forward to making this technology available to our global customer base," commented Theresa S. Creasey, Ph.D., Vice President of Sigma Custom Products, Sigma-Aldrich.
