ST. LOUIS, April 28 /PRNewswire-FirstCall/ -- Sigma-Aldrich (Nasdaq: SIAL) today announced the global release of MISSION(R) esiRNA, a pool of gene-specific siRNA that provides a novel and powerful approach to RNAi screening in mammalian cells. Unlike traditional synthetic RNAi, esiRNA (http://www.sigma.com/esirna) incorporates a pool of hundreds of siRNAs against a single gene target. This new tool is designed to eliminate the trial and error approach of identifying a single siRNA for gene knockdown and ensures minimal off-target effects.
"MISSION esiRNA provides a powerful way to elucidate gene function in cell culture assays," said Dr. Supriya Shivakumar, global marketing manager for Functional Genomics at Sigma-Aldrich. "The pooled format, unlike anything else on the market, should enable researchers to knock down genes rapidly and cost-effectively. This is an exciting addition to our current MISSION lineup and provides an effective technology that will facilitate RNAi research for a broad base of scientists."
The technique offers a number of benefits over the traditional approach to single-siRNA gene knockdown. By targeting each gene target with a "super-pool" of siRNA, the trial and error approach of identifying a useful single siRNA is eliminated. In addition, the approach should ensure minimal risk of off-target effects and enables the use of one assay per gene. Development of the esiRNA approach was supported by the German BMBF program "GO-Bio" and developed by the Max Planck Institute for Cell Biology and Genetics (MPI-CBG) in Dresden, Germany.
Frank Buchholz, a research group leader at the MPI-CBG, has pioneered the use of the esiRNA technology in RNAi screens. "We are delighted to be partnering with Sigma-Aldrich to make esiRNA technology available to the research community," he said. "esiRNAs were invented in Mike Bishop's laboratory at UCSF almost 10 years ago. esiRNA has been a major research focus of my group ever since. Sigma-Aldrich's extensive experience and product range in RNAi are a perfect complement to our effort to produce efficient and specific esiRNAs."
esiRNA are endoribonuclease-prepared siRNAs synthesized by in vitro transcription of a 300-600-bp gene specific double-stranded RNA, followed by enzymatic digestion. This collection of siRNA-like molecules is then purified, resulting in a complex pool of siRNA molecules all targeting different sequences of a single gene.

About Max Planck Institute: The Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) is one of 80 institutes of the Max Planck Society, an independent, non-profit organization in Germany. MPI-CBG was founded in 1998 and since February 2001, scientists from over 40 nations have been working under one roof. The Institute has a core staff of about 400 scientists, which form a network of 27 research groups covering different topics at the interface of cell biology and developmental biology including research investigating illnesses such as cancer or Alzheimer's disease. For example, at the MPI-CBG researchers study how the growth of cells is controlled and why this control process fails to function properly in cancer cells. Once science has an understanding of how cellular control systems work, currently incurable illnesses may be diagnosed earlier with a view to developing more effective treatments.
The MPI-CBG has forged partnerships with technology providers in many of its major areas of research since it believes that the greatest insight and new discoveries are made when innovations in new technologies allow problems in research to be addressed or investigated in new ways.
