Query the E. coli Community's Gene Expression Database (GenExpDB)
We have assembled all public E. coli microarray gene expression data on our new site.
Come visit the new GenExpDB to query 1000's of E. coli microarray experiments.
Hosted by the University of Oklahoma
Instructions:  Search E. coli GenExpDB using either gene name and/or b-number (multiple entries separate by comma or space).

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.
