Microarray Time Series Data for 102 E. Coli Genes Genes

Description

This data set describes the temporal expression of 102 genes of E. Coli after induction of the expression of SOD (recombinant human superoxide dismutase).

Usage

data(ecoli)

Format

caulobacter is a longitudinal object containing the data from the Schmidt-Heck et al. (2004) experiment. Essentially, this is a matrix with with 102 columns (=genes) and 9 rows (=time points). All expression levels are given in log2-ratios with respect to the first time point (i.e. the induction at time 0).

Source

The micoarray experiment was performed at the Institute of Applied Microbiology, University of Agricultural Sciences of Vienne. The data and the experiment is described in Schmidt-Heck et al. (2004).
