Series GSE5239 Query DataSets for GSE5239
Status Public on Jul 07, 2006
Title Expression data from Escherichia coli
Platform organism Escherichia coli K-12
Sample organism Escherichia coli
Experiment type Expression profiling by array
Summary Transcription profiles in BL21, BL21/pOri1 and BL21/pOri2 were analysed using DNA microarray technology. BL21, BL21/pOri1 or BL21/pOri2 strains were cultured at chemostat status and harvested after the cultivation arrived steady status.
Keywords: Effects of plasmid DNA on Escherichia coli metabolism
Overall design BL21, BL21/pOri1 and BL21/pOri2 were cultured at the exponential growth status or at the same growth rate status, respectively. E. coli BL21, BL21/pOri1 and BL21/pOri2 RNAs were reverse-transcripted into cDNAs, The RNAs from the BL21, BL21/pOri1, BL21/pOri2 were labelled with biotin. The labelled cDNAs were mixed and then hybridized on the microarray slides. Experiments were repeated four times. Most of them have no significant difference comparing plasmid-carrying E. coli and plasmid-free E. coli
