Figure 2From: An oral recombinant Salmonella enterica serovar Typhimurium mutant elicits systemic antigen-specific CD8+ T cell cytokine responses in miceGFP expression by the Salmonella vaccine vector. Recombinant Salmonella expressing GFP (AroC+GFP) or Salmonella carrying an empty plasmid (AroC+pGEM) were grown overnight. GFP expression by the bacteria was determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (A) and confirmed by Western Blotting (B).Back to article page
