Figure 1 Agarose gel electrophoresis analysis of recombinant pIRES-hpaA.
Lane 1: PCR product of pIRES as a negative control; lane 2: PCR product of pIRES-hpaA; lane 3: pIRES-hpaA after digestion with EcoR I and Mlu I; lane 4: pIRES after digestion with Eco RI and Mlu I; lane 5: DNA Marker (DL2000+15000).
Figure 2 Agarose gel electrophoresis analysis of recombinant attenuated Salmonella typhimurium DNA vaccine strain with restriction enzyme digestion.
Lane 1: DNA ladder (1 kb); lanes 2-5: Recombinant plasmid pIRES-hpaA from strains of different generations after digestion with EcoRI and Mlu I; lane 6: pIRES after digestion with EcoRI and Mlu I.
Figure 3 Identification of recombinant attenuated Salmonella typhimurium DNA vaccine strain carrying hpaA by PCR.
Lane 1: Product amplified from pIRES as a negative control; lane 2: Marker (DL2000+15000); lanes 3-4: Products amplified from recombinant plasmid from strains of different generations by PCR.
