Figure 2From: Production of recombinant protein by a novel oxygen-induced system in Escherichia coli Western blot of GFP production at 5 h of cultures shown in Figure 1 . Lane 1, pAB828 induced with 0.5 mM IPTG; lane 2, pAB49 induced by increasing dO2 up to 300%; lane 3, pAB49 maintained at 30% dO2; lane 4, pAB49 controlled at 0% dO2; lane 5, pAB43 negative control with 0.5 mM IPTG. M is molecular weight standard.Back to article page
