Figure 1From: Comparative proteomic analysis of Salmonella enterica serovar Typhimurium ppGpp-deficient mutant to identify a novel virulence protein required for intracellular survival in macrophagesAgarose 2-DE reference map of the S . Typhimurium strain SH100, prepared using a 12% gel focused on high-molecular-mass proteins (A) and a 15% gel focused on low-molecular-mass proteins (B). Strain SH100 was grown under amino acid starvation as described previously [26]. Gels are stained with Coomassie Brilliant Blue. Identified spots are numbered (corresponding to the spot numbers in additional file: 1. Proteins identified on the reference map).Back to article page
