Gene expression data has been collected by NCBI on a select few organisms for various experimental conditions. This microarray data has been clustered on NCBI's Gene Expression Omnibus (GEO) and can be viewed for the available experiments on prokaryotic organisms as of July 2004 (E. coli, R. sphaeroides, S. typhi). To view the current complete list of experiments click here, to visit NCBI.
Click the following links to view the expression data for the given experiment and the clustered results will open in a new browser window. Use the moveable orange view bar to highlight interesting portions of the clustered data you wish to view. Double click selected portions to zoom in on. Relationships created by expression results are displayed to the left and the experiments are along the top. Once you have picked out interesting clusters obtain the gene IDs to the right and enter them here , to perform a synonym search.
