Figure 1From: Compound DNA vaccine encoding SAG1/ SAG3 with A2/B subunit of cholera toxin as a genetic adjuvant protects BALB/c mice against Toxoplasma gondiiThe schematic diagram of the construction of DNA vaccines. SAG1 gene, SAG3 gene of T. gondii and CTXA2/B gene of cholera toxin were introduced into the eukaryotic expression plasmid pcDNA3.1 (−) vector by EcoR I / BamH I, EcoR I / Kpn I or EcoR I / Hind III cloning sites.Back to article page
