Figure 2From: Immunization of mice by Hollow Mesoporous Silica Nanoparticles as carriers of Porcine Circovirus Type 2 ORF2 ProteinThe expression of GST-ORF2-E protein. GST-ORF2-E protein was analyzed by (a) SDS-PAGE and (b) Western blot with an anti-GST monoclonal antibody. Lane 1: the third elution; Lane 2: the second elution; Lane 3: the first elution; Lane 4, supernatant of cell lysate after sonication; Lane 5: cell pellet after sonication; Lane 6: BL21 cells lysate after induction of IPTG; Lane 7, BL21 cells lysate before induction of IPTG. A clear band of 29 kDa was observed after induction.Back to article page
