Series GSE4631 Query DataSets for GSE4631
Status Public on May 30, 2006
Title Effect of ppGpp on Salmonella Typhimurium gene expression
Platform organism Salmonella enterica subsp. enterica serovar Typhimurium str. LT2
Sample organisms Salmonella enterica subsp. enterica serovar Typhimurium; Salmonella enterica subsp. enterica serovar Typhimurium str. SL1344
Experiment type Expression profiling by array
Summary The expression profile of an S. Typhimurium mutant strain unable to synthesise ppGpp (relAspoT deletions) was compared to the wild-type strain. The effect of ppGpp on virulence gene expression was studied under 4 different growth conditions that induce virulence gene expression.
Keywords: genetic modification
 
Overall design Study comprised 4 separate experiments (with 2 strains and 4 replicates for each strain per growth condition). The experiments were indirect comparisons using Salmonella genomic DNA as the comparator which also acted as the control for spot quality.
