PortEco: Expression holds post-publication microarray gene expression data from E. coli experiments. Our goal is to provide free access to all published E. coli expression data. If you would like to use PortEco: Expression to share your expression data, please contact us.
Many of the search items below require a search term. Some of the queries expect a gene locus term such as ’lacZ' (without the quotes). Wildcard characters, '*' and '%' may also be used. For example ’lac*' (without quotes).
February 20, 2013: We are in the process of migrating published E. coli microarray data into PortEco: Expression. Currently we have 2056 published microarrays from 117 publications. For more information about our import plans, please refer to our progress page.
