"With over half a million users worldwide interested in science, including around 200,000 that are researchers or that are interested in Biology, Facebook provides an outstanding platform to connect scientists and a significant audience for Sigma-Aldrich to interact," said Dr. David Smoller, President of Sigma-Aldrich's Research Biotech business unit. "The 'Your Favorite Gene' portal provides the scientific basis for that connection and we hope 'What's Your Favorite Gene?' fosters a culture of information exchange and collaboration within the life science community. We plan to continue expanding the online dialogue of researchers and will be developing additional ways to connect scientists in the coming months."

The biological information that supports the 'What's Your Favorite Gene?' Facebook application is provided by Sigma-Aldrich's 'Your Favorite Gene powered by Ingenuity.' Launched in January 2009, 'Your Favorite Gene powered by Ingenuity' has won awards for its interactive nature, setting it apart from static biological search options available in the life science market. 'Your Favorite Gene powered by Ingenuity' contains interactive pathways and gene interaction maps for over 90,000 genes mapped to relevant products such as antibodies, RNA interference (shRNA and siRNA), small molecules, proteins, and peptides. The portal enables researchers to model experiments and to search by gene, protein, function, disease, species, tissue or pathway by providing access to a curated database of biological information.
