Immunogenicity and Protective Efficacy of a Novel Recombinant BCG Strain Overexpressing Antigens Ag85A and Ag85B
Figure 1
Recombinant prokaryotic expression plasmids pPro85A and pPro85B (a) and the purification of recombinant Ag85A and Ag85B proteins (b). The final products of recombinant Ag85A and Ag85B proteins were confirmed by SDS-PAGE and stained with a Coomassie blue dye. Lane M, protein molecular size marker (kDa); lane 1, the final products of Ag85A (32 kDa); lane 2, the final products of Ag85B (30 kDa).
