Polyplus-transfection宣布的发展ZNA™, a New Class of Modified Oligonucleotides

Polyplus-transfection has announced that it has developed a new class of cationic oligonucleotides. These are called “ZNA™” and have a promising potential in molecular biology. Polyplus owns the intellectual property.

Polyplus has recently established proof of concept showing that ZNA™ used as detection probes improve PCR technology performance. In particular, ZNA™ increase the sensitivity of tests and the ability to detect mutations.

As well as presenting a similar efficacy to the best modified oligonucleotides on the market, ZNA™ possess major advantages compared to competing products.

ZNA™ offer an increased affinity for nucleic acids without losing selectivity and therefore will improve the performance of other molecular hybridization techniques such as in situ hybridization and microarrays. They could also be used for in vitro detection of micro-RNAs, a new class of intracellular effectors.

“Polyplus is extending its activities from transfection reagents to molecular biology tools for research and diagnostics,” said Joelle Bloch, CEO of Polyplus-transfection. “Our next step will be to market ZNA™ via a network of firms specialized in this field. We are also actively seeking partners to help us develop a range of applications for ZNA™.”

Polyplus-transfection will present its first results in a talk entitled “ZNA™: New High-Affinity Synthetic Oligonucleotides as Powerful Tools for PCR” at the international Advances in qPCR conference taking place in Stockholm Sweden, September 17-18 2008.
