Welcome to the University of Oklahoma's E. coli Gene Expression Database
Instructions:  Search E. coli GenExpDB using either gene name and/or b-number (multiple entries separated by comma or space).
Example:  edd • b3517 • laca,lacy,lacz • 416366 (location)

Heatmap Legend:  Gene Expression Ratios are displayed colorimetrically. Blue/Red indicates genes which are induced and Yellow/Green indicates genes which are repressed (in the experimental condition compared to the control); the log2 ratios are scaled 2*standard deviation from the average logratio and darken to black to indicate no change in expression.   Hovering over a spot will display the logratio value and the ExperimentSet : Experiment.
Display:  Clicking on a heatmap bar will display either a graph, omics view or ERing of all infomation for that Experiment. Select Graph (default) to display experiment in a scatter plot. Select Omics ( EcoCyc ) to display an overlay of the transcriptome data on the metabolic pathway chart. Select ERing to view regulatory networks.
