Fig. 5From: Molecular dynamics simulation and experimental study of the surface-display of SPA protein via Lpp-OmpA system for screening of IgGSDS-PAGE analysis showing efficiency of E. coli Lpp′-ompA-SpA compared to the Protein A-agarose, stained by Coomassie Brilliant Blue R. M:Protein marker, 1–3: different concentrations of expressed recombinant Lpp′-ompA was loaded, 4–5: different concentrations of expressed recombinant Lpp’-ompA-Spa was loaded, 6–7: different concentrations of the purified rabbit IgG from serum using recombinant E. coli Lpp′-ompA-SpA after elution was loaded, 8: purified rabbit IgG from serum using protein A-agarose as a controlBack to article page
