PortEco : Expression


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).
