The effect of LacP/O regulation on relative phage titer and Fab display. The infected cells were exposed to (1) 1% glucose, (2) 0.5% glucose and 500 μM IPTG, (3) 0.5% glucose, (4) 0.2% glucose, (5) 0.1% glucose, (6) 0.05% glucose, (7) 0.025% glucose, (8) no supplement, (9) 10 μM IPTG, (10) 100 μM IPTG and (11) 250 μM IPTG. Black bar: phage and white bar: Fab. The results are based on three independent experiments with standard deviation shown.
