Figure 3From: Production of recombinant protein by a novel oxygen-induced system in Escherichia coli Oxyblot detection of GFP expression from E. coli pAB828 induced with 0.5 mM IPTG at 300% (lane 1) and 30% of dO 2 (lane 2). M refers to molecular weight standards. Lane 4 and 5, negative controls of samples of Lanes 1 and 2. Negative controls were not subjected to the derivatization reaction.Back to article page
