KIRKLAND, WA -- Rosetta Biosoftware today announced that Aventis Pharmaceuticals, Inc., the U.S. business of Frankfurt, Germany-based Aventis Pharma AG, has licensed the Rosetta Resolver(R) Gene Expression Data Analysis System. The Rosetta Resolver system is an enterprise bioinformatics solution for gene expression research developed by Rosetta Biosoftware and distributed by Rosetta and Agilent Technologies, Inc. (NYSE:A). The Rosetta Resolver system can be used with a variety of third party and internally developed DNA microarray technologies, including Agilent DNA microarrays. Dr. Christoph Brockel, head of Aventis Pharma's Informatics group in Cambridge, Massachusetts, and leader of Aventis' Gene Expression Informatics project, said, "We selected the Rosetta Resolver system because of its high performance, multidimensional analysis capabilities and customizability. In addition, the Rosetta Resolver system's ability to be networked into a multi-server global solution for our distributed enterprise was important to us." "Rosetta Biosoftware is pleased to welcome Aventis as the newest member of our esteemed list of customers," said Dr. Douglas E. Bassett, Jr., vice president and general manager of Rosetta Biosoftware. "Aventis joins some of the world's leading life sciences companies, including Bristol-Myers Squibb, GlaxoSmithKline and Merck & Co., Inc., whose gene expression research efforts have been empowered by the Rosetta Resolver system." The Rosetta Resolver system provides high-capacity data storage, retrieval and analysis of gene expression data. The system is ideal for life science research organizations that need to assess compound specificity or toxicity, identify new genes or therapeutic targets, or compare and analyze large databases of expression profiles. The Rosetta Resolver system combines flexibility and ease of use with high-performance algorithms to produce an enterprise solution for rapid analysis of gene expression data. The system can accept and analyze data from a wide variety of expression profiling formats, including Agilent DNA microarrays, and applies Rosetta Biosoftware's proprietary error models to yield quality statistics for every gene expression measurement. These statistics are automatically leveraged by all analysis tools, ensuring reliable results. For additional information visit www.rosettabio.com
