WebP.895 caption of figure 4: "Owing to high voltage (18 kV/ cm) electroporation, ~95% of cells are killed at each cycle. Hence, the electroporation event serves to both introduce oligos into cells and to dilute the cell population, cells are then recovered and grown to mid-log phase (7 × 10^8 cells/ ml) in liquid medium for the subsequent cycle." WebWhen IPTG was added at OD600 = 0.1 and cultures were maintained at 4°C for 48-72 h, the soluble protein yield was 3 fold higher than that obtained in the mid-log phase (OD600 = 0.6). Besides, the target protein expression increased and the endogenous bacterial proteins reduced, thus making the protein purification process easier and more efficient.
